+\title{Numerical Analysis of a 1-Dimensional
+Immersed-Boundary\\ Method}
+
+\abstract{We present the numerical analysis of a simplified,
+one-dimensional version
+of Peskin's immersed boundary method, which has been used to
+solve
+the two- and three-dimensional Navier-Stokes equations in the
+presence of immersed boundaries. We consider the heat
+equation
+ in a finite domain with a moving source term.
+We denote the solution as $u(x,t)$ and the location of the
+source
+ term as $X(t)$. The source term is a moving delta function
+whose strength is a function of u at the location of the
+delta function.
+The p.d.e. is coupled to an ordinary differential equation
+whose
+solution gives the location of the source term.
+ The o.d.e. is $X'(t) = u(X(t),t)$, which can be interpreted as
+saying the source term moves at the local velocity.
+The accuracy the numerical method of solution depends on how
+the
+delta function is discretized when the delta function is not
+at
+a grid point and on how the solution, u, is represented
+ at locations between grid points. We present results showing
+the effect of different choices of spreading the source to
+the grid and
+of restricting the solution to the source location.
+The problem we analyze is also similar to the Stefan problem
+and
+the immersed-boundary method has features in common with
+particle-in-cell
+ methods.}

+
+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. There are no new tags. Existing LaTeX tags have been formatted to
+%% match the Proceedings series style.
+%%
+%% 2. You must use \cite in the text to mark your reference citations and
+%% \bibitem in the listing of references at the end of your chapter. See
+%% the examples in the following file. The file siam.bst has been
+%% included for use with BiBTeX. Please be sure to include the appropriate
+%% .bib file with BiBTeX submissions. You may also submit the .bbl file
+%% instead of the .bib file.
+%%
+%% 3. Unless otherwise stated by your editor, do your chapter as if it
+%% is Chapter 1. The appropriate chapter number will be included during
+%% the production of the proceedings.
+%%
+%% 4. This macro is set up for three levels of headings (\section,
+%% \subsection, and \subsubsection). The macro will automatically number
+%% the headings for you.
+%%
+%% 5. The running heads are indicated by the \markboth command. Please
+%% define the running heads by placing the authors last names in the
+%% first field and the title of the paper in the second field.
+%% They should be typed initial cap and lower case. Please see the example.
+%% Neither field can contain more than 50 characters including spaces,
+%% so please use a shortened version of the title if necessary. For
+%% papers with multiple authors please follow these rules; for
+%% two authors type {Author 1 and Author 2}; for more that two authors type
+%% {Author 1 et al.}.
+%%
+%% 6. Theorems, Lemmas, Definitions, etc. are to be double-numbered,
+%% indicating the section and the occurrence of that element
+%% within that section. (For example, the first theorem in the second
+%% section would be numbered 2.1. The macro will
+%% automatically do the numbering for you.
+%%
+%% 7. Proofs are handled with the commands \begin{proof}\end{proof}.
+%% If you wish to use an end of proof box, use \qed preceding \end{proof}.
+%% The example uses one. It is not required.
+%%
+%% 8. Figures, equations, and tables must be single-numbered. All equation
+%% numbers are to be on the left. Figure captions should be placed under
+%% the figures they pertain to. Table captions should be placed above
+%% the tables. Use existing LaTeX tags for these elements. Numbering of
+%% these elements will be done automatically. SIAM supports the use of
+%% psfig for including Postscript figures. All Postscript figures should be
+%% sent as separate files. A hardcopy version of all Postscript figures
+%% is also required. See note regarding this under How to Submit Your Paper.
+%%
+%% 9. Grant information and author affiliations.
+%% This information is included in the file with the two commands,
+%% \thanks and \footnotemark []. (See example). The \thanks command
+%% produces a footnote for the title or author, and places the
+%% appropriate footnote symbol with the title or author and at the
+%% bottom of the page. The \footnotemark [] command allows the use of
+%% duplicate footnote symbols. This macro follows the normal LaTeX order
+%% of footnote symbols. Below is a list of these symbols, and their
+%% corresponding footnotemark:
+%%
+%% asterisk \footnotemark[1]
+%% single-dagger \footnotemark[2]
+%% double-dagger \footnotemark[3]
+%% section sign \footnotemark[4]
+%% paragraph \footnotemark[5]
+%% parallel \footnotemark[6]
+%% double asterisk \footnotemark[7]
+%% double single-dagger \footnotemark[8]
+%% double double-dagger \footnotemark[9]
+%%
+%% The following general rules for grants and affiliations apply:
+%% a) If there is a single grant for the paper, then the grant
+%% information should be footnoted to the title.
+%% b) If there is more than one grant, include the grant information
+%% with each author's affiliation.
+%% c) If there are different grants for the paper but the authors share
+%% the same affiliation, footnote the grant information to the title.
+%% For example, The work of the first author was supported by xyz.
+%% The work of the second author was supported by abc. And so on.
+%% d) For authors sharing the same affiliation, use \thanks for the
+%% first author with that affiliation and the appropriate
+%% \footnotemark[] (from the list above) for all subsequent authors
+%% with that affiliation.
+%%
+%% 10. Special fonts.
+%% SIAM supports the use of AMS-TeX fonts version 2.0 and later. As
+%% described in the manual for these fonts, they can be included by
+%% \input{amssym.def} and \input{amssym.tex}. These macros are not yet
+%% updated to make use of the New Font Selection Scheme (NFSS) of
+%% Mittelbach and Schopf. To make these macros compatible with NFSS, use
+%% the oldlfont style option.
+%%
+%% 11. How to Submit Your Paper.
+%% The electronic version of your paper should be sent to proceed@siam.org.
+%% A hardcopy version must also be submitted. Instructions are included

+\begin{abstract}An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability. \end{abstract}
+\section{Problem Specification}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+\cos \sin A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+\begin{theorem} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\end{theorem}

+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+
+\begin{proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening in each of the three
+independent variables and then ignoring the intermediate
+grids; this artifice simplifies coding considerably.\qed

+sparse elimination algorithm given in \cite{BANKSMITH}.

+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination.
+
+\begin{lemma} We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.
+\end{lemma}
+
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+\cite{EISENSTAT} - \cite{LIU2}, \cite{ROSE76}, \cite{SCHREIBER}.
+
+\subsection{Robustness}
+We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+This section assumes prior knowledge of the role of graph theory
+in sparse Gaussian elimination; surveys of this role are
+available in \cite{ROSE72} and \cite{GEORGELIU}. More general
+discussions of elimination trees are given in
+\cite{LAW} - \cite{LIU2}, \cite{SCHREIBER}.
+Thus, at the $k$th stage, the bordering algorithm consists of
+solving the lower triangular system
+\begin{equation} \label{1.2}
+ L_{k-1}v = c
+\end{equation}
+and setting
+\begin{eqnarray}
+\ell &=& D^{-1}_{k-1}v , \\
+\delta &=& \alpha - \ell^{t} v .
+\end{eqnarray}
+
+\subsubsection{Versatility.} We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+
+\section{Conclusions} The special
+structure of this problem allows us to make exact estimates of
+the complexity. For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations
+\cite{GEORGELIU}, \cite{ROSEWHITTEN}. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+
+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. There are no new tags. Existing LaTeX tags have been formatted to
+%% match the Proceedings series style.
+%%
+%% 2. You must use \cite in the text to mark your reference citations and
+%% \bibitem in the listing of references at the end of your chapter. See
+%% the examples in the following file. The file siamproc.bst has been
+%% included for use with BiBTeX. Please be sure to include the appropriate
+%% .bib file with BiBTeX submissions. You may also submit the .bbl file
+%% instead of the .bib file.
+%%
+%% 3. Unless otherwise stated by your editor, do your chapter as if it
+%% is Chapter 1. The appropriate chapter number will be included during
+%% the production of the proceedings.
+%%
+%% 4. This macro is set up for three levels of headings (\section,
+%% \subsection, and \subsubsection). The macro will automatically number
+%% the headings for you.
+%%
+%% 5. The running heads are indicated by the \markboth command. Please
+%% define the running heads by placing the authors last names in the
+%% first field and the title of the paper in the second field.
+%% They should be typed initial cap and lower case. Please see the example.
+%% Neither field can contain more than 50 characters including spaces,
+%% so please use a shortened version of the title if necessary. For
+%% papers with multiple authors please follow these rules; for
+%% two authors type {Author 1 and Author 2}; for more that two authors type
+%% {Author 1 et al.}.
+%%
+%% 6. Theorems, Lemmas, Definitions, etc. are to be double-numbered,
+%% indicating the section and the occurrence of that element
+%% within that section. (For example, the first theorem in the second
+%% section would be numbered 2.1. The macro will
+%% automatically do the numbering for you.
+%%
+%% 7. Proofs are handled with the commands \begin{proof}\end{proof}.
+%% If you wish to use an end of proof box, use \qed preceding \end{proof}.
+%% The example uses one. It is not required.
+%%
+%% 8. Figures, equations, and tables must be single-numbered. All equation
+%% numbers are to be on the left. Figure captions should be placed under
+%% the figures they pertain to. Table captions should be placed above
+%% the tables. Use existing LaTeX tags for these elements. Numbering of
+%% these elements will be done automatically. SIAM supports the use of
+%% psfig for including Postscript figures. All Postscript figures should be
+%% sent as separate files. A hardcopy version of all Postscript figures
+%% is also required. See note regarding this under How to Submit Your Paper.
+%%
+%% 9. Grant information and author affiliations.
+%% This information is included in the file with the two commands,
+%% \thanks and \footnotemark []. (See example). The \thanks command
+%% produces a footnote for the title or author, and places the
+%% appropriate footnote symbol with the title or author and at the
+%% bottom of the page. The \footnotemark [] command allows the use of
+%% duplicate footnote symbols. This macro follows the normal LaTeX order
+%% of footnote symbols. Below is a list of these symbols, and their
+%% corresponding footnotemark:
+%%
+%% asterisk \footnotemark[1]
+%% single-dagger \footnotemark[2]
+%% double-dagger \footnotemark[3]
+%% section sign \footnotemark[4]
+%% paragraph \footnotemark[5]
+%% parallel \footnotemark[6]
+%% double asterisk \footnotemark[7]
+%% double single-dagger \footnotemark[8]
+%% double double-dagger \footnotemark[9]
+%%
+%% The following general rules for grants and affiliations apply:
+%% a) If there is a single grant for the paper, then the grant
+%% information should be footnoted to the title.
+%% b) If there is more than one grant, include the grant information
+%% with each author's affiliation.
+%% c) If there are different grants for the paper but the authors share
+%% the same affiliation, footnote the grant information to the title.
+%% For example, The work of the first author was supported by xyz.
+%% The work of the second author was supported by abc. And so on.
+%% d) For authors sharing the same affiliation, use \thanks for the
+%% first author with that affiliation and the appropriate
+%% \footnotemark[] (from the list above) for all subsequent authors
+%% with that affiliation.
+%%
+%% 10. Special fonts.
+%% SIAM supports the use of AMS-TeX fonts version 2.0 and later. As
+%% described in the manual for these fonts, they can be included by
+%% \input{amssym.def} and \input{amssym.tex}. These macros are not yet
+%% updated to make use of the New Font Selection Scheme (NFSS) of
+%% Mittelbach and Schopf. To make these macros compatible with NFSS, use
+%% the oldlfont style option.
+%%
+%% 11. How to Submit Your Paper.
+%% The electronic version of your paper should be sent to proceed@siam.org.
+%% A hardcopy version should also be submitted. Instructions are included
+%% in your acceptance letter. Please be sure to send hardcopy
+%% versions of any Postscript figures you have submitted electronically.
+%% Be sure to return your signed Copyright Transfer Agreement. We cannot
+%% publish your paper without it.

+\begin{abstract}An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability. \end{abstract}
+\section{Problem Specification}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+\cos \sin A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+\begin{theorem} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\end{theorem}

+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+
+\begin{proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening in each of the three
+independent variables and then ignoring the intermediate
+grids; this artifice simplifies coding considerably.\qed

+\begin{lemma} We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.
+\end{lemma}
+
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+\cite{EISENSTAT} - \cite{LIU2}, \cite{ROSE76}, \cite{SCHREIBER}.
+
+\subsection{Robustness}
+We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+This section assumes prior knowledge of the role of graph theory
+in sparse Gaussian elimination; surveys of this role are
+available in \cite{ROSE72} and \cite{GEORGELIU}. More general
+discussions of elimination trees are given in
+\cite{LAW} - \cite{LIU2}, \cite{SCHREIBER}.
+Thus, at the $k$th stage, the bordering algorithm consists of
+solving the lower triangular system
+\begin{equation} \label{1.2}
+ L_{k-1}v = c
+\end{equation}
+and setting
+\begin{eqnarray}
+\ell &=& D^{-1}_{k-1}v , \\
+\delta &=& \alpha - \ell^{t} v .
+\end{eqnarray}
+
+\subsubsection{Versatility.} We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+
+\section{Conclusions} The special
+structure of this problem allows us to make exact estimates of
+the complexity. For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations
+\cite{GEORGELIU}, \cite{ROSEWHITTEN}. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+
+\author{Leslie Lamport}
+\date{17 February 1987}
+\begin{document}
+\maketitle
+
+\section{How to Use \MakeIndex}
+
+\MakeIndex\ is a program for
+making an index in a document generated with \LaTeX. The first step in
+producing the index is to put the necessary \verb|\index| commands in
+your document, as described in the next section. Here, I describe how
+to generate the index after the \verb|\index| commands are in place.
+
+Let's suppose that the root file of your document is {\tt myfile.tex}.
+You must make the following changes to your document:
+\begin{itemize}
+
+\item Add the {\tt makeidx} document-style option to the list of
+options in the \verb|\documentstyle| command. (See page 21 of the
+\LaTeX\ manual.)
+
+\item Put a \verb|\makeindex| command in the preamble (between the
+ \linebreak%%%%%
+\verb|\documentstyle| and \verb|\begin{document}| commands).
+
+\item Put a \verb|\printindex| command where you want the index to
+appear---usually at the end, right before the \verb|\end{document}|
+command.
+\end{itemize}
+You then run \LaTeX\ on your entire document, causing it to
+generate the file {\tt myfile.idx}, which I will call the {\tt idx} file.
+Next, run the \MakeIndex\ program by
+typing the following Unix command:
+\begin{quote}
+ {\tt makeindex myfile.idx}
+\end{quote}
+This produces the file {\tt myfile.ind}, which I will call the {\tt
+ind} file. If \MakeIndex\ generated no error messages, you can now rerun
+\LaTeX\ on your document and the index will appear. (You can remove
+the \verb|\makeindex| command first so the {\tt idx} file is not
+regenerated.) If there were error messages, see
+Section~\ref{sec:errors}.
+
+By reading the index, you may discover additional mistakes. These should be
+corrected by changing the appropriate \verb|\index| commands in the
+document and regenerating the {\tt ind} file. If there are
+problems that cannot be corrected in this way, you can always edit
+the {\tt ind} file directly. However, such editing is to be
+avoided because it must be repeated every time you generate a new
+version of the index.
+
+
+\section{How to Generate Index Entries}
+
+\subsection{When, Why, What, and How to Index}
+
+It's tempting to generate the index as you write the document. Resist
+the temptation. It is virtually impossible to obtain any consistency
+in an index that is generated in this way.
+
+An index is there to help the reader find what he's looking for. With
+this in mind, common sense can help in figuring out what should be in
+the index and how it should be organized. Since it's often hard to
+distinguish common sense from equally common nonsense, professional
+advice is useful. Many style guides discuss indexing; the pamphlet
+{\em Indexing Your Book\/} by Sina Spiker (The University of Wisconsin
+Press, 1954) is, according to its subtitle, ``A Practical
+Guide for Authors''.
+
+Unfortunately, these guides to indexing seem to have been written when
+high tech meant using a ball-point pen instead of a quill, so their
+advice on the mechanics of creating an index revolve around how to
+stack your $3\times 5$ index cards. You'll have to figure out your own
+method of using the computer to lighten the chore. An alphabetical
+list of every word in your document, with duplicates removed, is not a
+bad place to start. If your system has Howard Trickey's {\tt delatex}
+program, then the following Unix command generates such a list from the
+file {\tt myfile.tex} and puts it on the file {\tt foo}:
+\begin{quote}
+\tt delatex myfile.tex | sort -uf > foo
+\end{quote}
+
+The computer is only a tool; it can't write the index for you. It may
+be easy to choose which words are important and mechanically generate
+an index citing every occurrence of those words, but the resulting
+index will not be as useful to the reader as one prepared with more
+care.
+
+
+
+
+\subsection{The Basics}
+
+Each \verb|\index| command causes \LaTeX\ to write an entry on the {\tt
+idx} file. The following example shows some simple
+\verb|\index| commands and the index entries that they produce. The
+page number refers to the page containing the text where the
+\verb|\index| command appears.\footnote{To avoid any ambiguity if a
+page break occurs right at an {\tt \symbol{'134}index} command, it's a
+good idea to attach the command to a word instead of putting it between
+words.}
+\begin{iexample}
+Page ii & \verb|\index{Alpha}| \\
+Page viii: & \verb|\index{alpha}| \\
+Page ix: & \verb|\index{alpha}| \\
+ & \verb|\index{Alphabet}| \\
+Page 22: & \verb|\index{alpha}| \\
+ & \verb|\index{alphas}| \\
+Page 23: & \verb|\index{alphabet}| \\
+ & \verb|\index{alphabet}| \\
+Page 24: & \verb|\index{alpha bet}|
+\sindex
+Alpha, ii \\
+alpha, viii, ix, 22 \\
+alpha bet, 24\\
+Alphabet, ix\\
+alphabet, 23\\
+alphas, 22
+\end{iexample}
+Note that the duplicate \verb|\index{alphabet}| commands on
+page 23 produce only one ``23'' in the index.
+
+
+To produce a subentry, the argument of the \verb|\index|
+command should contain both the main entry and the subentry, separated
+by a \verb|!| character.
+\begin{iexample}
+Page 7: & \verb|\index{gnat!size of}| \\
+Page 32: & \verb|\index{gnat}| \\
+Page 35: & \verb|\index{gnat!anatomy}| \\
+ & \verb|\index{gnus!good}| \\
+Page 38: & \verb|\index{gnus!bad}| \\
+ &
+\sindex
+gnat, 32 \\
+\sitem anatomy, 35 \\
+\sitem size of, 7\\
+gnus \\
+\sitem bad, 38\\
+\sitem good, 35
+\end{iexample}
+You can also have subsubentries.
+\begin{iexample}
+Page 8: & \verb|\index{bites!animal!gnats}| \\
+Page 10: & \verb|\index{bites!animal!gnus}| \\
+Page 12 : & \verb|\index{bites!vegetable}| \\
+ & \\
+ &
+\sindex
+bites \\
+\sitem animal \\
+\ssitem gnats, 8 \\
+\ssitem gnus, 10 \\
+\sitem vegetable, 12
+\end{iexample}
+\LaTeX\ and \MakeIndex\ support only three levels of indexing; you
+can't have subsubsubentries.
+
+
+To specify a page range, put an \verb/\index{...|(}/
+command at the beginning of the range and an \verb/\index{...|)}/
+command at the end of the range.
+\begin{iexample}
+Page vi: & \verb/\index{gnat|(}/ \\
+Page x: & \verb/\index{gnat|)}/ \\
+Page 22: & \verb|\index{gnat}| \\
+ & \verb/\index{gnus!bad|(}/ \\
+ & \verb/\index{gnus!bad|)}/ \\
+Page 28: & \verb/\index{gnus!good|(}/ \\
+Page 30: & \verb|\index{gnus!good}| \\
+Page 32: & \verb/\index{gnus!good|)}/
+\sindex
+gnat, vi--x, 22 \\
+gnus \\
+\sitem bad, 22\\
+\sitem good, 28--32
+\end{iexample}
+Note that \MakeIndex\ does the right thing when both ends of the range
+fall on the same page.\footnote{The use of ``28ff.'' rather than
+``28--32'' is frowned upon by the experts.}
+
+Sometimes, you want to add a cross-reference with no page
+number. This is done as follows;
+\begin{iexample}
+Page 2: & \verb|\index{at}| \\
+Page 2: & \verb/\index{at!bat|see{bat, at}}/
+\sindex
+at, 2 \\
+\sitem bat, {\em see\/} bat, at
+\end{iexample}
+Since the ``see'' entry does not print any page number, it doesn't
+matter where the \verb/\index{...|see{...}}/ command goes, so
+long as it follows the \verb|\begin{document}| command. You
+might want to put all such cross-referencing commands in one place.
+
+
+If you specify an entry of the form $\sigma$\verb|@|$\tau$, the string
+$\sigma$ determines the alphabetical position of the entry, while the
+string $\tau$ produces the text of the entry.
+\begin{iexample}
+Page 44: & \verb|\index{twenty}| \\
+Page 46: & \verb|\index{twenty-one}| \\
+Page 55: & \verb|\index{twenty@xx}|
+\sindex
+twenty, 44 \\
+xx, 55 \\
+twenty-one, 46
+\end{iexample}
+This feature is useful because the argument of the \verb|\index|
+command provides the actual input string that \LaTeX\ uses to generate
+the index entry. In the following example, the input \verb|$\alpha$|
+produces the symbol $\alpha$,
+\begin{iexample}
+Page 12: & \verb|\index{alphas}| \\
+Page 13: & \verb|\index{alpha}| \\
+Page 14: & \verb|\index{alpha@$\alpha$}|
+\sindex
+alpha, 13 \\
+$\alpha$, 14 \\
+alphas, 12
+\end{iexample}
+Similarly, the command \verb|\index{gnu@{\bf gnu}}| produces
+a boldface {\bf gnu} index entry.
+
+In some indexes, certain page numbers are specially formatted---for
+example, an italic page number may indicate the primary reference, and
+an {\em n\/} after a page number may denote that the item appears in a
+footnote on that page. \MakeIndex\ makes it easy to format an
+individual page number any way you want. For any string of characters
+$\sigma$, the command \verb/\index{...|/$\sigma$\verb|}| produces a
+page number of the form \verb|\|$\sigma$\verb|{|$n$\verb|}|.
+Similarly, the command \verb/\index{...|(/$\sigma$\verb|}| may produce
+a page number of the form \verb|\|$\sigma$\verb|{|$n$--$m$\verb|}|.
+Thus, suppose the document contains the following command definitions:
+\begin{quote}
+\verb|\newcommand{\ii}[1]{{\it #1}}| \\
+\verb|\newcommand{\nn}[1]{#1n}|
+\end{quote}
+We could then have:
+\begin{iexample}
+Page 3: & \verb/\index{gnat|ii}/ \\
+Page 4: & \verb/\index{gnat|nn}/ \\
+Page 5: & \verb/\index{gnu}/ \\
+Page 44: & \verb/\index{gnu|(ii}/ \\
+Page 46: & \verb/\index{gnu|)}/
+\sindex
+gnat, {\em 3}, 4n \\
+gnu, 5, {\em 44--46}
+\end{iexample}
+The ``see'' option is a special case of this facility, where the
+\verb|\see| command is predefined by the {\tt makeidx} document-style
+option.
+
+
+\subsection{The Fine Print}
+
+Commands in an index entry are expanded when the index is typeset,
+not when the {\tt idx} file is written. Hence, the command
+\verb|\index{\gnu}| produces an entry that is alphabetized by
+\verb|\gnu|, regardless of how the \verb|\gnu| command is defined.
+
+Recall that special characters like \verb|\| may appear in the argument
+of an \verb|\index| command only if that command is not itself
+contained in the argument of another command. This is most likely to
+be a problem when indexing items in a footnote. Even in this case,
+robust commands can be placed in the ``\verb|@|'' part of an entry, as
+in \verb|\index{gnu@{\it gnu}}|, and fragile commands can be used
+if protected with the \verb|\protect| command.\footnote{In
+versions of \LaTeX\ released before 3 February 1987, you must
+use the {\tt\symbol{'134}string} command instead of
+{\tt\symbol{'134}protect}.}
+
+Remember that the argument of an \verb|\index| command must always have
+matching braces, where the brace in a \verb|\{| or \verb|\}| command
+counts.
+
+\MakeIndex\ assumes that all page numbers are either arabic or lower-case
+roman numerals; it assumes that pages numbered with roman numerals
+precede those numbered with arabic numerals.
+
+To put a \verb|!|, \verb|@|, or \verb/|/ character in an index entry,
+{\em quote\/} it by preceding the character with a \verb|"|. More
+precisely, any a character is said to be quoted if it follows an
+unquoted \verb|"| that is not part of a \verb|\"| command. A quoted
+\verb|!|, \verb|@|, or \verb/|/ character is treated like an
+ordinary character rather than having its usual meaning. The
+\verb|"| preceding a quoted character is deleted before the
+entries are alphabetized.
+\begin{iexample}
+Page 2: & \verb|\index{exclaim ("!)}| \\
+Page 3: & \verb|\index{exclaim ("!)!loudly}| \\
+Page 4: & \verb|\index{fur@f\"{u}r}| \\
+Page 5: & \verb|\index{quote (\verb+""+)}|
+\sindex
+exclaim (!), 2 \\
+\sitem loudly, 3\\
+f\"{u}r, 4\\
+quote (\verb+""+), 5
+\end{iexample}
+
+
+\MakeIndex\ regards spaces as ordinary characters when alphabetizing the
+entries and deciding whether two entries are the same. Thus, letting
+``\verb*| |'' denote a space character, the commands
+\verb*|\index{gnu}|, \verb*|\index{ gnu}|, and \verb*|\index{gnu }|
+produce three separate entries, the first appearing near the beginning
+of the index, since \verb*| | comes before any letter in \MakeIndex's
+``alphabetical'' order. All three entries look the same when
+printed, since \LaTeX\ ignores extra spaces in the input. Similarly,
+ \verb*|\index{a space}| and \verb*|\index{a space}| produce two
+different entries that look the same when printed. Do not
+split the argument of an \verb|\index| command across lines in the
+input file.
+
+
+
+\section{Error Messages} \label{sec:errors}
+
+\MakeIndex\ types out on the terminal the number of lines read and
+written and how many errors were found. Message to identify the error
+are written on a file with extension {\tt ilg}. There are two phases
+in which \MakeIndex\ can produce error messages: when it is reading the
+{\tt idx} file, and when it is writing the {\tt ind} file. Each error
+message prints the nature of the error followed by a line number,
+identifying where in the file the error occurs. In the reading phase,
+the line number refers to the {\tt idx} file; in the writing phase, it
+refers to the {\tt ind} file.
+
+\subsection{Errors in Reading Phase}
+
+\subsubsection*{\tt Extra `!' at position ...}
+
+The \verb|\index| command's argument has more than two unquoted
+\verb|!| characters. Perhaps some of them should be quoted.
+
+\subsubsection*{\tt Extra `@' at position ...}
+
+The \verb|\index| command argument has two or more unquoted \verb|@|
+characters with no intervening \verb|!|. Perhaps one of the \verb|@|
+characters should be quoted.
+
+\subsubsection*{\tt Extra `|' at position ...}
+
+The \verb|\index| command's argument has more than one unquoted \verb|!|
+characters. Perhaps the extras should be quoted.
+
+\subsubsection*{\tt Illegal null field}
+
+The \verb|\index| command argument doesn't make sense because some
+string is null that shouldn't be. The command \verb|\index{!big}| will
+produce this error, since it specifies a subentry ``big'' with no
+entry. Similarly, the command \verb|\index{@big}| is incorrect because
+it specifies a null string for alphabetizing.
+
+%\subsubsection*{\tt No \symbol{'134}indexentry}
+%
+%Each line of an {\tt idx} file written by \LaTeX\ should contain an
+%\verb|\indexentry| command. \MakeIndex\ has found a line in the {\tt idx}
+%file that does not contain an \verb|\indexentry| command. The {\tt
+%idx} file has probably been corrupted.
+%
+%\subsubsection*{\tt Missing \symbol{'173}}
+%
+%\MakeIndex\ believes that the braces in the argument of the \verb|\index|
+%command are not properly matched. Since \LaTeX\ must
+%have thought that the braces were properly matched, the problem
+%is probably due to a corrupted {\tt idx} file.
+%
+%\subsubsection*{\tt Missing \symbol{'175}}
+%
+%See ``{\tt Missing \symbol{'173}}'' error.
+
+\subsubsection*{\tt Argument ... too long (max 1024).}
+
+Your document contained an \verb|\index| command with a very long
+argument. You probably forgot the right brace that was supposed
+to delimit the argument.
+
+\subsubsection*{Other errors}
+
+\MakeIndex\ can produce a variety of other error messages indicating
+that something is seriously wrong with the {\tt idx} file. If you
+get one, it probably means that the {\tt idx} file was corrupted in
+some way. If \LaTeX\ did not generate any errors when it created
+the {\tt idx} file, then it is highly unlikely to have produced
+a bad {\tt idx} file. If it did, you'll have to examine the
+{\tt idx} file to figure out what went wrong.
+
+
+\subsection{Errors in Writing Phase}
+
+\subsubsection*{\tt Unmatched range opening operator}
+
+An \verb/\index{...|(}/ command was not followed by a matching
+ \linebreak%%%%%
+\verb/\index{...|)}/ command. The ``\verb|...|'' in the two
+commands must be completely identical.
+
+
+\subsubsection*{\tt Unmatched range closing operator }
+
+An \verb/\index{...|(}/ command was not preceded by a matching
+ \linebreak%%%%%
+\verb/\index{...|)}/ command.
+
+\subsubsection*{\tt Extra range opening operator }
+
+Two \verb/\index{...|(}/ commands appear in the document with no intervening
+\verb/\index{...|)}/ command.
+
+
+
+\subsubsection*{\tt Inconsistent page encapsulator ... within range}
+
+\MakeIndex\ has been instructed to include a page range for an entry
+and a single page number within that range that is formatted
+differently---for example, by having a
+\verb+\index{gnu|ii}+ command between a \verb+\index{gnu|(}+
+and a \verb+\index{gnu|)}+ command.
+
+
+\subsubsection*{\tt Conflicting entries}
+
+\MakeIndex\ thinks it has been instructed to print the same page number
+twice in two different ways---for example, by the commands
+\verb|\index{gnu}| and \verb/\index{gnu|(see{...}}/ appearing on the
+same page.
+

+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. There are no new tags. Existing LaTeX tags have been formatted to
+%% match the Proceedings series style.
+%%
+%% 2. You must use \cite in the text to mark your reference citations and
+%% \bibitem in the listing of references at the end of your chapter. See
+%% the examples in the following file. The file siamproc.bst has been
+%% included for use with BiBTeX.
+%%
+%% 3. This macro is set up for three levels of headings (\section,
+%% \subsection, and \subsubsection). The macro will automatically number
+%% the headings for you.
+%%
+%% 4. Theorems, Lemmas, Definitions, etc. are to be double-numbered,
+%% indicating the section and the occurrence of that element
+%% within that section. (For example, the first theorem in the second
+%% section would be numbered 2.1. The macro will
+%% automatically do the numbering for you.
+%%
+%% 5. Proofs are handled with the commands \begin{proof}\end{proof}.
+%% If you wish to use an end of proof box, use \qed preceding \end{proof}.
+%% The example uses one. It is not required.
+%%
+%% 6. Figures, equations, and tables must be single-numbered. All equation
+%% numbers are to be on the left. Figure captions should be placed under
+%% the figures they pertain to. Table captions should be placed above
+%% the tables. Use existing LaTeX tags for these elements. Numbering of
+%% these elements will be done automatically.
+%%
+%% 7. Grant information and author affiliations.
+%% This information is included in the file with the two commands,
+%% \thanks and \footnotemark []. (See example). The \thanks command
+%% produces a footnote for the title or author, and places the
+%% appropriate footnote symbol with the title or author and at the
+%% bottom of the page. The \footnotemark [] command allows the use of
+%% duplicate footnote symbols. This macro follows the normal LaTeX order
+%% of footnote symbols. Below is a list of these symbols, and their
+%% corresponding footnotemark:
+%%
+%% asterisk \footnotemark[1]
+%% single-dagger \footnotemark[2]
+%% double-dagger \footnotemark[3]
+%% section sign \footnotemark[4]
+%% paragraph \footnotemark[5]
+%% parallel \footnotemark[6]
+%% double asterisk \footnotemark[7]
+%% double single-dagger \footnotemark[8]
+%% double double-dagger \footnotemark[9]
+%%
+%% The following general rules for grants and affiliations apply:
+%% a) If there is a single grant for the paper, then the grant
+%% information should be footnoted to the title.
+%% b) If there is more than one grant, include the grant information
+%% with each author's affiliation.
+%% c) If there are different grants for the paper but the authors share
+%% the same affiliation, footnote the grant information to the title.
+%% For example, The work of the first author was supported by xyz.
+%% The work of the second author was supported by abc. And so on.
+%% d) For authors sharing the same affiliation, use \thanks for the

+\begin{abstract}An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability. \end{abstract}
+\section{Problem Specification}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+\cos \sin A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+\begin{theorem} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\end{theorem}

+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+
+\begin{proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening in each of the three
+independent variables and then ignoring the intermediate
+grids; this artifice simplifies coding considerably.\qed

+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination.
+
+\begin{lemma} We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.
+\end{lemma}
+
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+\cite{EISENSTAT} - \cite{LIU2}, \cite{ROSE76}, \cite{SCHREIBER}.
+
+\subsection{Robustness}
+We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+This section assumes prior knowledge of the role of graph theory
+in sparse Gaussian elimination; surveys of this role are
+available in \cite{ROSE72} and \cite{GEORGELIU}. More general
+discussions of elimination trees are given in
+\cite{LAW} - \cite{LIU2}, \cite{SCHREIBER}.
+Thus, at the $k$th stage, the bordering algorithm consists of
+solving the lower triangular system
+\begin{equation} \label{1.2}
+ L_{k-1}v = c
+\end{equation}
+and setting
+\begin{eqnarray}
+\ell &=& D^{-1}_{k-1}v , \\
+\delta &=& \alpha - \ell^{t} v .
+\end{eqnarray}
+
+\subsubsection{Versatility.} We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+
+\section{Conclusions} The special
+structure of this problem allows us to make exact estimates of
+the complexity. For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations
+\cite{GEORGELIU}, \cite{ROSEWHITTEN}. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. There are no new tags. Existing LaTeX tags have been formatted to
+%% match the Proceedings series style.
+%%
+%% 2. You must use \cite in the text to mark your reference citations and
+%% \bibitem in the listing of references at the end of your chapter. See
+%% the examples in the following file. The file siamproc.bst has been
+%% included for use with BiBTeX.
+%%
+%% 3. This macro is set up for three levels of headings (\section,
+%% \subsection, and \subsubsection). The macro will automatically number
+%% the headings for you.
+%%
+%% 4. Theorems, Lemmas, Definitions, etc. are to be double-numbered,
+%% indicating the section and the occurrence of that element
+%% within that section. (For example, the first theorem in the second
+%% section would be numbered 2.1. The macro will
+%% automatically do the numbering for you.
+%%
+%% 5. Proofs are handled with the commands \begin{proof}\end{proof}.
+%% If you wish to use an end of proof box, use \qed preceding \end{proof}.
+%% The example uses one. It is not required.
+%%
+%% 6. Figures, equations, and tables must be single-numbered. All equation
+%% numbers are to be on the left. Figure captions should be placed under
+%% the figures they pertain to. Table captions should be placed above
+%% the tables. Use existing LaTeX tags for these elements. Numbering of
+%% these elements will be done automatically.
+%%
+%% 7. Grant information and author affiliations.
+%% This information is included in the file with the two commands,
+%% \thanks and \footnotemark []. (See example). The \thanks command
+%% produces a footnote for the title or author, and places the
+%% appropriate footnote symbol with the title or author and at the
+%% bottom of the page. The \footnotemark [] command allows the use of
+%% duplicate footnote symbols. This macro follows the normal LaTeX order
+%% of footnote symbols. Below is a list of these symbols, and their
+%% corresponding footnotemark:
+%%
+%% asterisk \footnotemark[1]
+%% single-dagger \footnotemark[2]
+%% double-dagger \footnotemark[3]
+%% section sign \footnotemark[4]
+%% paragraph \footnotemark[5]
+%% parallel \footnotemark[6]
+%% double asterisk \footnotemark[7]
+%% double single-dagger \footnotemark[8]
+%% double double-dagger \footnotemark[9]
+%%
+%% The following general rules for grants and affiliations apply:
+%% a) If there is a single grant for the paper, then the grant
+%% information should be footnoted to the title.
+%% b) If there is more than one grant, include the grant information
+%% with each author's affiliation.
+%% c) If there are different grants for the paper but the authors share
+%% the same affiliation, footnote the grant information to the title.
+%% For example, The work of the first author was supported by xyz.
+%% The work of the second author was supported by abc. And so on.
+%% d) For authors sharing the same affiliation, use \thanks for the
+%% first author with that affiliation and the appropriate
+%% \footnotemark[] (from the list above) for all subsequent authors
+%% with that affiliation.

+\begin{abstract}An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability. \end{abstract}
+\section{Problem Specification}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+\cos \sin A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+\begin{theorem} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\end{theorem}

+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+
+\begin{proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening in each of the three
+independent variables and then ignoring the intermediate
+grids; this artifice simplifies coding considerably.\qed

+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination.
+
+\begin{lemma} We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.
+\end{lemma}
+
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+\cite{EISENSTAT} - \cite{LIU2}, \cite{ROSE76}, \cite{SCHREIBER}.
+
+\subsection{Robustness}
+We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+This section assumes prior knowledge of the role of graph theory
+in sparse Gaussian elimination; surveys of this role are
+available in \cite{ROSE72} and \cite{GEORGELIU}. More general
+discussions of elimination trees are given in
+\cite{LAW} - \cite{LIU2}, \cite{SCHREIBER}.
+Thus, at the $k$th stage, the bordering algorithm consists of
+solving the lower triangular system
+\begin{equation} \label{1.2}
+ L_{k-1}v = c
+\end{equation}
+and setting
+\begin{eqnarray}
+\ell &=& D^{-1}_{k-1}v , \\
+\delta &=& \alpha - \ell^{t} v .
+\end{eqnarray}
+
+\subsubsection{Versatility.} We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+
+\section{Conclusions} The special
+structure of this problem allows us to make exact estimates of
+the complexity. For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations
+\cite{GEORGELIU}, \cite{ROSEWHITTEN}. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+%% 7. Grant information and author affiliations.
+%% This information is included in the file with the two commands,

+%% appropriate footnote symbol with the title or author and at the
+%% bottom of the page. The \footnotemark [] command allows the use of
+%% duplicate footnote symbols. This macro follows the normal LaTeX order
+%% of footnote symbols. Below is a list of these symbols, and their
+%% corresponding footnotemark:
+%%
+%% asterisk \footnotemark[1]
+%% single-dagger \footnotemark[2]
+%% double-dagger \footnotemark[3]
+%% section sign \footnotemark[4]
+%% paragraph \footnotemark[5]
+%% parallel \footnotemark[6]
+%% double asterisk \footnotemark[7]
+%% double single-dagger \footnotemark[8]
+%% double double-dagger \footnotemark[9]
+%%
+%% The following general rules for grants and affiliations apply:
+%% a) If there is a single grant for the paper, then the grant
+%% information should be footnoted to the title.
+%% b) If there is more than one grant, include the grant information
+%% with each author's affiliation.
+%% c) If there are different grants for the paper but the authors share
+%% the same affiliation, footnote the grant information to the title.
+%% For example, The work of the first author was supported by xyz.
+%% The work of the second author was supported by abc. And so on.
+%% d) For authors sharing the same affiliation, use \thanks for the
+%% first author with that affiliation and the appropriate
+%% \footnotemark[] (from the list above) for all subsequent authors
+%% with that affiliation.

+\begin{abstract}An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability. \end{abstract}
+\section{Problem Specification}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+\cos \sin A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+\begin{theorem} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\end{theorem}

+Since our interest here does not

+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+
+\begin{proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening in each of the three
+independent variables and then ignoring the intermediate
+grids; this artifice simplifies coding considerably.\qed

+
+\begin{lemma} We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.
+\end{lemma}
+
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+\cite{EISENSTAT} - \cite{LIU2}, \cite{ROSE76}, \cite{SCHREIBER}.
+
+\subsection{Robustness}
+We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+This section assumes prior knowledge of the role of graph theory
+in sparse Gaussian elimination; surveys of this role are
+available in \cite{ROSE72} and \cite{GEORGELIU}. More general
+discussions of elimination trees are given in
+\cite{LAW} - \cite{LIU2}, \cite{SCHREIBER}.
+Thus, at the $k$th stage, the bordering algorithm consists of
+solving the lower triangular system
+\begin{equation} \label{1.2}
+ L_{k-1}v = c
+\end{equation}
+and setting
+\begin{eqnarray}
+\ell &=& D^{-1}_{k-1}v , \\
+\delta &=& \alpha - \ell^{t} v .
+\end{eqnarray}
+
+\subsubsection{Versatility.} We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+
+\section{Conclusions} The special
+structure of this problem allows us to make exact estimates of
+the complexity. For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations
+\cite{GEORGELIU}, \cite{ROSEWHITTEN}. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+% This is proc2e.tex, an example file for use with the SIAM LaTeX2e
+% Proceedings Series macros.
+% Please take the time to read the following comments, as they describe
+% how to use these macros. This file can be composed and printed out for
+% use as sample output.
+
+% Any comments or questions regarding these macros should be directed to:

+% This file is to be used as an example for style only. It should not be read
+% for content.
+
+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. There are no new tags. Existing LaTeX tags have been formatted to
+%% match the Proceedings series style.
+%%
+%% 2. You must use \cite in the text to mark your reference citations and
+%% \bibitem in the listing of references at the end of your chapter. See
+%% the examples in the following file. The file siamproc.bst has been
+%% included for use with BiBTeX.
+%%
+%% 3. This macro is set up for three levels of headings (\section,
+%% \subsection, and \subsubsection). The macro will automatically number
+%% the headings for you.
+%%
+%% 4. Theorems, Lemmas, Definitions, etc. are to be double-numbered,
+%% indicating the section and the occurrence of that element
+%% within that section. (For example, the first theorem in the second
+%% section would be numbered 2.1. The macro will
+%% automatically do the numbering for you.
+%%
+%% 5. Proofs are handled with the commands \begin{proof}\end{proof}.
+%% If you wish to use an end of proof box, use \qed preceding \end{proof}.
+%% The example uses one. It is not required.
+%%
+%% 6. Figures, equations, and tables must be single-numbered. All equation
+%% numbers are to be on the left. Figure captions should be placed under
+%% the figures they pertain to. Table captions should be placed above
+%% the tables. Use existing LaTeX tags for these elements. Numbering of
+%% these elements will be done automatically.
+%%
+%% 7. Grant information and author affiliations.
+%% This information is included in the file with the two commands,
+%% \thanks and \footnotemark []. (See example). The \thanks command
+%% produces a footnote for the title or author, and places the
+%% appropriate footnote symbol with the title or author and at the

+\begin{abstract}An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability. \end{abstract}
+\section{Problem Specification}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+\cos \sin A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+\begin{theorem} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\end{theorem}

+\begin{proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening in each of the three
+independent variables and then ignoring the intermediate
+grids; this artifice simplifies coding considerably.\qed

+
+\begin{lemma} We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.
+\end{lemma}
+
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+\cite{EISENSTAT} - \cite{LIU2}, \cite{ROSE76}, \cite{SCHREIBER}.
+
+\subsection{Robustness}
+We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+This section assumes prior knowledge of the role of graph theory
+in sparse Gaussian elimination; surveys of this role are
+available in \cite{ROSE72} and \cite{GEORGELIU}. More general
+discussions of elimination trees are given in
+\cite{LAW} - \cite{LIU2}, \cite{SCHREIBER}.
+Thus, at the $k$th stage, the bordering algorithm consists of
+solving the lower triangular system
+\begin{equation} \label{1.2}
+ L_{k-1}v = c
+\end{equation}
+and setting
+\begin{eqnarray}
+\ell &=& D^{-1}_{k-1}v , \\
+\delta &=& \alpha - \ell^{t} v .
+\end{eqnarray}
+
+\subsubsection{Versatility.} We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+
+\section{Conclusions} The special
+structure of this problem allows us to make exact estimates of
+the complexity. For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations
+\cite{GEORGELIU}, \cite{ROSEWHITTEN}. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+\title Numerical Analysis of a 1-Dimensional
+Immersed-Boundary Method\\
+
+\abstract We present the numerical analysis of a simplified,
+one-dimensional version
+of Peskin's immersed boundary method, which has been used to
+solve
+the two- and three-dimensional Navier-Stokes equations in the
+presence of immersed boundaries. We consider the heat
+equation
+ in a finite domain with a moving source term.
+We denote the solution as $u(x,t)$ and the location of the
+source
+ term as $X(t)$. The source term is a moving delta function
+whose strength is a function of u at the location of the
+delta function.
+The p.d.e. is coupled to an ordinary differential equation
+whose
+solution gives the location of the source term.
+ The o.d.e. is $X'(t) = u(X(t),t)$, which can be interpreted as
+saying the source term moves at the local velocity.
+The accuracy the numerical method of solution depends on how
+the
+delta function is discretized when the delta function is not
+at
+a grid point and on how the solution, u, is represented
+ at locations between grid points. We present results showing
+the effect of different choices of spreading the source to
+the grid and
+of restricting the solution to the source location.
+The problem we analyze is also similar to the Stefan problem
+and
+the immersed-boundary method has features in common with
+particle-in-cell
+ methods.\\

+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6]. In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special
+structure of this problem allows us to make exact estimates of
+the complexity. To our knowledge, the m-tree previously has not been applied in this

+% Use \headtwo for second level headings. They will be numbered automatically.

+\headtwo{Robustness}In \S 1.2, we review the bordering algorithm, and introduce

+\headtwo{Versatility} In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special

+% Use \headthree for third level headings.
+
+\headthree{Complexity.}For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+% The command \Refs sets the word Reference as a heading and allows the proper
+% amount of space before the start of the references. Each reference must
+% begin with \ref\\. The article or title of the reference should be in
+% italic. Use the \it command within brackets. End each reference with
+% \endref and allow two returns between references. Use the command
+% \sameauthor (see reference 8) when the same author or group of authors
+% is listed consecutively.

+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. You must use the numbered reference style([1],[2]), listing the
+%% references at the end of the chapter either by order of citation
+%% or alphabetically.
+%%
+%% 2. This macro is set up for three levels of headings. Use the commands
+%% \headone, \headtwo, and \headthree. The macro will automatically
+%% number the headings.
+%%
+%% 3. Theorems, Lemmas, Definitions, etc. are to be double-numbered,
+%% indicating the section and the occurrence of that element
+%% within that section. (For example, the first theorem in the second
+%% section would be numbered 2.1.) This numbering must
+%% be done manually.
+%%
+%% 4. Proofs are handled by \prf\endprf. If you want to use an end-of-proof
+%% box, insert \qed right before the \endprf command.
+%%
+%% 5. Figures and equations must be manually single-numbered. Use \leqno
+%% for equation numbering. The macro provides the \fig for including
+%% figures. This command consists of three fields. The first field is
+%% used for inserting the appropriate space for the figure. The second
+%% field is the figure number. The third field is the caption. See the
+%% example included in this file. SIAM supports the use of psfig for
+%% including Postscript figures. All Postscript figures should be sent
+%% as separate files. A hardcopy version of all Postscript figures is
+%% also required. See note regarding this under How to Submit Your Paper.
+%%
+%% 6. Use of \title\endtitle and \lasttitle\endlastitle.
+%% This macro package provides two possible commands for handling the
+%% title of your paper. The commands \title\endtitle should be used for
+%% all lines except the last line of multiple line titles. The commands
+%% \lasttitle\endlasttitle should be used for the last line of multiple
+%% line titles. In the case of a single line title, \lasttitle\endlasttitle
+%% should be used.
+%%
+%% 7. Use of \author\endauthor and \lastauthor\endlastauthor.
+%% As in the title macro, two possible commands are provided for the
+%% author. The commands \author\endauthor should be used for the first
+%% line of authors if there are more than one line. The commands
+%% \lastauthor\endlastauthor should be used for the last line
+%% of multiple lines of authors. In the case of a single line of authors,
+%% \lastauthor\endlastauthor should be used. A maximum of four authors
+%% should be placed on any one line. The appropriate space must also be
+%% hard coded between authors on the same line. The spacing is as follows:
+%%
+%% If 2 authors; \hskip4pc between
+%% If 3 authors; \hskip3pc between
+%% If 4 authors; \hskip2pc between
+%%
+%% 8. Grant information and author affiliations.
+%% This information is included by using the \footnote command and the
+%% appropriate footnote symbol. SIAM uses footnote symbols in a
+%% particular order. Below is a list of these symbols:
+%%
+%% asterisk
+%% single-dagger
+%% double-dagger
+%% section sign
+%% paragraph
+%% parallel
+%% double asterisk
+%% double single-dagger
+%% double double-dagger
+%%
+%% For illustrative purposes, all footnote symbols have been used in the
+%% example file.
+%%
+%% A note regarding \footnote. This command seems to leave extra white
+%% space between footnotes. This is quite evident in the example file. If
+%% any user of these macros has a solution to this problem, I would
+%% appreciate hearing from you. Send your comments to: gray@siam.org.
+%%
+%% The following general rules apply for including grants and affiliations:
+%% a) If there is a single grant for the paper, then the grant
+%% information should be footnoted to the title.
+%% b) If there is more than one grant, included the grant information
+%% with each authors affiliation.
+%% c) If there are different grants for the paper but the authors share
+%% the same affiliation, footnote the grant information to the title.
+%% For example, The work of the first author was supported by xyz.
+%% The work of the second author was supported by abc. And so on.

+\centerline{\bf Abstract}
+\abstract An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability.\endabstract
+
+
+\headone{Problem Specification}
+In this paper, we consider the solution of the $N \times N$ linear
+system
+$$A x = b\leqno (1)$$
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+$$
+P A P^{t} = L D L^{t}
+\leqno (2)$$
+
+\noindent where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\headone{Design Considerations}
+Several good ordering algorithms (nested dissection and minimum degree)
+are available for computing $P$ [1], [2].
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+% Use \thm and \endthm for theorems. They must be numbered manually.
+% Lemmas (\lem \endlem), corollaries (\cor \endcor), and
+% propositions (\prop \endprop) are coded the same as theorems and must
+% also be numbered manually.
+
+\thm{Theorem 2.1.} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\endthm

+% Use \prf and \endprf to begin and end a proof.
+% The use of \qed will produce an end-of-proof box.
+
+\prf{Proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening each.\qed\endprf

+\lem{Lemma 2.1.}We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.

+% Use \fig to insert space for figures .

+\fig{10pc}{Fig. 1}{This is the caption for figure one.}
+
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6]. In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special
+structure of this problem allows us to make exact estimates of
+the complexity. To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6].
+
+% Use \headtwo for second level headings. They will be numbered automatically.
+
+\headtwo{Robustness}In \S 1.2, we review the bordering algorithm, and introduce
+the sorting and intersection problems that arise in the
+sparse formulation of the algorithm.
+
+\headtwo{Versatility} In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special
+structure of this problem allows us to make exact estimates of
+the complexity. To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6].
+
+
+% Use \headthree for third level headings.
+
+\headthree{Complexity.}For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.
+
+% The command \Refs sets the word Reference as a heading and allows the proper
+% amount of space before the start of the references. Each reference must
+% begin with \ref\\. The article or title of the reference should be in
+% italic. Use the \it command within brackets. End each reference with
+% \endref and allow two returns between references. Use the command
+% \sameauthor (see reference 8) when the same author or group of authors
+% is listed consecutively.

+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. You must use the numbered reference style([1],[2]), listing the
+%% references at the end of the chapter either by order of citation
+%% or alphabetically.
+%%
+%% 2. This macro is set up for three levels of headings. Use the commands
+%% \headone, \headtwo, and \headthree. The macro will automatically
+%% number the headings.
+%%
+%% 3. Theorems, Lemmas, Definitions, etc. are to be double-numbered,
+%% indicating the section and the occurrence of that element
+%% within that section. (For example, the first theorem in the second
+%% section would be numbered 2.1.) This numbering must
+%% be done manually.
+%%
+%% 4. Proofs are handled by \prf\endprf. If you want to use an end-of-proof
+%% box, insert \qed right before the \endprf command.
+%%
+%% 5. Figures and equations must be manually single-numbered. Use \leqno
+%% for equation numbering. The macro provides the \fig for including
+%% figures. This command consists of three fields. The first field is
+%% used for inserting the appropriate space for the figure. The second
+%% field is the figure number. The third field is the caption. See the
+%% example included in this file. SIAM supports the use of psfig for
+%% including Postscript figures. All Postscript figures should be sent
+%% as separate files. A hardcopy version of all Postscript figures is
+%% also required. See note regarding this under How to Submit Your Paper.
+%%
+%% 6. Use of \title\endtitle and \lasttitle\endlastitle.
+%% This macro package provides two possible commands for handling the
+%% title of your paper. The commands \title\endtitle should be used for
+%% all lines except the last line of multiple line titles. The commands
+%% \lasttitle\endlasttitle should be used for the last line of multiple
+%% line titles. In the case of a single line title, \lasttitle\endlasttitle
+%% should be used.
+%%
+%% 7. Use of \author\endauthor and \lastauthor\endlastauthor.
+%% As in the title macro, two possible commands are provided for the
+%% author. The commands \author\endauthor should be used for the first
+%% line of authors if there are more than one line. The commands
+%% \lastauthor\endlastauthor should be used for the last line
+%% of multiple lines of authors. In the case of a single line of authors,
+%% \lastauthor\endlastauthor should be used. A maximum of four authors
+%% should be placed on any one line. The appropriate space must also be
+%% hard coded between authors on the same line. The spacing is as follows:
+%%
+%% If 2 authors; \hskip4pc between
+%% If 3 authors; \hskip3pc between
+%% If 4 authors; \hskip2pc between
+%%
+%% 8. Grant information and author affiliations.
+%% This information is included by using the \footnote command and the
+%% appropriate footnote symbol. SIAM uses footnote symbols in a
+%% particular order. Below is a list of these symbols:
+%%
+%% asterisk
+%% single-dagger
+%% double-dagger
+%% section sign
+%% paragraph
+%% parallel
+%% double asterisk
+%% double single-dagger
+%% double double-dagger
+%%
+%% For illustrative purposes, all footnote symbols have been used in the
+%% example file.
+%%
+%% A note regarding \footnote. This command seems to leave extra white
+%% space between footnotes. This is quite evident in the example file. If
+%% any user of these macros has a solution to this problem, I would
+%% appreciate hearing from you. Send your comments to: gray@siam.org.
+%%
+%% The following general rules apply for including grants and affiliations:
+%% a) If there is a single grant for the paper, then the grant
+%% information should be footnoted to the title.
+%% b) If there is more than one grant, included the grant information
+%% with each authors affiliation.
+%% c) If there are different grants for the paper but the authors share
+%% the same affiliation, footnote the grant information to the title.
+%% For example, The work of the first author was supported by xyz.
+%% The work of the second author was supported by abc. And so on.

+\centerline{\bf Abstract}
+\abstract An equivalence is shown between realizability of input/output (i/o) operators by
+rational control systems and high-order algebraic differential equations for
+i/o pairs. This generalizes, to nonlinear systems, the equivalence
+between autoregressive representations and finite dimensional linear
+realizability.\endabstract
+
+
+\headone{Problem Specification}
+In this paper, we consider the solution of the $N \times N$ linear
+system
+$$A x = b\leqno (1)$$
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+$$
+P A P^{t} = L D L^{t}
+\leqno (2)$$
+
+\noindent where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\headone{Design Considerations}
+Several good ordering algorithms (nested dissection and minimum degree)
+are available for computing $P$ [1], [2].
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,

+\section{Problem Specification.}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations.}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.

+\section{Problem Specification.}In this paper, we consider the solution of the $N \times
+N$ linear
+system
+\begin{equation} \label{e1.1}
+A x = b
+\end{equation}
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of (\ref{e1.1}) by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+\[
+P A P^{t} = L D L^{t}
+\]
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+
+\section{Design Considerations.}Several good ordering algorithms (nested dissection and
+minimum degree)
+are available for computing $P$ \cite{GEORGELIU}, \cite{ROSE72}.
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+\begin{theorem} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\end{theorem}
+
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in \cite{BANKSMITH}.

+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.

+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+\begin{proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening in each of the three
+independent variables and then ignoring the intermediate
+grids; this artifice simplifies coding considerably.

+\begin{lemma} We discuss first the choice for $I_{k-1}^k$
+which is a generalization. We assume that $G^{k-1}$ is
+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.

+
+To our knowledge, the m-tree previously has not been applied in this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6]. In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special

+\subsection{Robustness.}\ We do not
+attempt to present an overview
+here, but rather attempt to focus on those results that
+are relevant to our particular algorithm.
+This section assumes prior knowledge of the role of graph theory
+in sparse Gaussian elimination; surveys of this role are
+available in \cite{ROSE72} and \cite{GEORGELIU}. More general
+discussions of elimination trees are given in
+\cite{LAW} - \cite{LIU2}, \cite{SCHREIBER}.
+Thus, at the $k$th stage, the bordering algorithm consists of
+solving the lower triangular system
+\begin{equation} \label{1.2}
+ L_{k-1}v = c
+\end{equation}
+and setting
+\begin{eqnarray}
+\ell &=& D^{-1}_{k-1}v , \\
+\delta &=& \alpha - \ell^{t} v .

+
+%%%%%%%%%%%%%%% PLEASE NOTE THE FOLLOWING STYLE RESTRICTIONS %%%%%%%%%%%%%%%
+
+%% 1. You must use the numbered reference style([1],[2]), listing the
+%% references at the end of the chapter either by order of citation
+%% or alphabetically.
+%%
+%% 2. Unless otherwise stated by your editor, do your chapter as if it
+%% is Chapter 1.
+%% If you know which number your chapter is, you must do the following:
+%%
+%% Go into the style file (ptexfrnt.sty) and search for the
+%% \def\chapter#1 definition. At the end of this definition
+%% there is a command \headcount=1. Change the 1 to
+%% the appropriate number. This change will cause the headings
+%% in your chapter to match the chapter number.
+%%
+%% 3. This macro is set up for two levels of headings. The macro will
+%% automatically number the headings for you.
+%%
+%% 4. The running heads are defined in the output routine. It will be
+%% necessary for you to alter the information currently included.
+%% To do this, go into the style file and search for OUTPUT. Once there,
+%% scroll through the file until you see the command \def\rhead. Replace
+%% CHAPTER TITLE with the title (or shortened title) of your paper.
+%% Replace AUTHORS NAMES with the appropriate names.
+%% Neither running head may be longer than 50 characters.
+%%
+%% 5. Theorems, Lemmas, Definitions, etc. are to be triple numbered,
+%% indicating the chapter, section, and the occurence of that element
+%% within that section. (For example, the first theorem in the second
+%% section of chapter three would be numbered 3.2.1. This numbering must
+%% be done manually.
+%%
+%% 6. Figures and equations must be manually double-numbered, indicating
+%% chapter and occurence. Use \leqno for equation numbering. See the
+%% example of \caption for figure numbering.
+%% Note. Although not shown, tables must also be double-numbered. The
+%% command \caption can also be used for table captions.
+%%
+%% 7. At the first occurence of each new element there is a description
+%% of how to use the coding.
+%%
+%%%%%%% PLEASE NOTE THE FOLLOWING POTENTIAL PROBLEMS:
+%
+%% 1. A bug exists that prevents a page number from printing on the first
+%% page of the paper. Please ignore this problem. It will be handled
+%% after you submit your paper.
+%%
+%% 2. The use of \topinsert and \midinsert to allow space for figures can
+%% result in unusual page breaks, or unusual looking pages in general.

+
+\headone{Problem Specification}
+In this paper, we consider the solution of the $N \times N$ linear
+system
+$$A x = b\leqno(1.1)$$
+where $A$ is large, sparse, symmetric, and positive definite. We consider
+the direct solution of by means of general sparse Gaussian
+elimination. In such a procedure, we find a permutation matrix $P$, and
+compute the decomposition
+$$
+P A P^{t} = L D L^{t}
+$$
+where $L$ is unit lower triangular and $D$ is diagonal.
+
+\headone{Design Considerations}
+Several good ordering algorithms (nested dissection and minimum degree)
+are available for computing $P$ [1], [2].
+Since our interest here does not
+focus directly on the ordering, we assume for convenience that $P=I$,
+or that $A$ has been preordered to reflect an appropriate choice of $P$.
+
+% Use \headtwo for second level headings. They will be numbered automatically.
+
+\headtwo{Robustness}In \S 1.2, we review the bordering algorithm, and introduce
+the sorting and intersection problems that arise in the
+sparse formulation of the algorithm.
+
+\headtwo{Versatility} In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special
+structure of this problem allows us to make exact estimates of
+the complexity. To our knowledge, the m-tree previously has not been applied in
+this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6].
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in [3].
+As was shown there, a general sparse elimination scheme based on the
+bordering algorithm requires less storage for pointers and
+row/column indices than more traditional implementations of general
+sparse elimination. This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+
+
+% Use \thm and \endthm for theorems. They must be numbered manually.
+% Lemmas (\lem \endlem), corollaries (\cor \endcor), and
+% propositions (\prop \endprop) are coded the same as theorems and must
+% also be numbered manually.
+
+\thm{Theorem 2.1.} The method was extended to three
+dimensions. For the standard multigrid
+coarsening
+(in which, for a given grid, the next coarser grid has $1/8$
+as many points), anisotropic problems require plane
+relaxation to
+obtain a good smoothing factor.\endthm

+
+% Use \prf to begin a proof.
+
+\prf{Proof} In this paper we consider two methods. The first method
+is
+basically the method considered with two differences:
+first, we perform plane relaxation by a two-dimensional
+multigrid method, and second, we use a slightly different
+choice of
+interpolation operator, which improves performance
+for nearly singular problems. In the second method coarsening
+is done by successively coarsening each.
+
+% Use \dfn to begin definitions.
+
+\dfn{Definition 1.2.1.}We describe the two methods in \S\ 1.2. This is a
+definition in the plain tex macro.
+
+This is accomplished by exploiting the m-tree,
+a particular spanning tree for the graph of the filled-in matrix.
+Our purpose here is to examine the nonnumerical complexity of the
+sparse elimination algorithm given in [3].

+For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+\lem{Lemma 2.1.}We discuss first the choice for $I_{k-1}^k$

+obtained
+from $G^k$
+by standard coarsening; that is, if $G^k$ is a tensor product
+grid $G_{x}^k \times G_{y}^k \times G_{z}^k$,
+$G^{k-1}=G_{x}^{k-1} \times G_{y}^{k-1} \times G_{z}^{k-1}$,
+where $G_{x}^{k-1}$ is obtained by deleting every other grid
+point of $G_x^k$ and similarly for $G_{y}^k$ and $G_{z}^k$.

+[4] - [10], [5], [6]. In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special
+structure of this problem allows us to make exact estimates of
+the complexity. To our knowledge, the m-tree previously has not been applied in
+this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6].
+
+% Use \headtwo for second level headings. They will be numbered automatically.
+
+\headone{Problem Solving}In \S 1.2, we review the bordering algorithm, and
+introduce
+the sorting and intersection problems that arise in the
+sparse formulation of the algorithm.
+
+\headtwo{Versatility} In \S 1.3., we analyze the complexity of the old and new
+approaches to the intersection problem for the special case of
+an $n \times n$ grid ordered by nested dissection. The special
+structure of this problem allows us to make exact estimates of
+the complexity. To our knowledge, the m-tree previously has not been applied in
+this
+fashion to the numerical factorization, but it has been used,
+directly or indirectly, in several optimal order algorithms for
+computing the fill-in during the symbolic factorization phase
+[4] - [10], [5], [6].
+
+
+\headtwo{Complexity}For the old approach, we show that the
+complexity of the intersection problem is $O(n^{3})$, the same
+as the complexity of the numerical computations. For the
+new approach, the complexity of the second part is reduced to
+$O(n^{2} (\log n)^{2})$.

+% The command \Refs sets the word Reference as a heading and allows the proper
+% amount of space before the start of the references. Each reference must
+% begin with \ref\\. The article or title of the reference should be in
+% italic. Use the \it command within brackets. End each reference with
+% \endref and allow two returns between references. Use the command
+% \sameauthor (see reference 8) when the same author or group of authors
+% is listed consecutively.
