+\abstract
+This sample paper illustrates many of the amstex
+macros as used with the \AmSTeX\ SIAM style file amstexsiam (version 2.0a).
+The \AmSTeX\ SIAM style file, which
+inputs and builds upon the amsppt style (version 2.1a or later)
+of Michael Spivak, gives authors easy
+access to most of the typographical constructions used in SIAM journals.
+It does not address the issues of the table of contents
+or tables, which must be set using more primitive \TeX\ macros.

+\subhead 1. Introduction\endsubhead
+We are concerned with numerical approximations to the so-called
+porous-medium equation \cite{6},
+$$
+\alignedat2
+ &u_t=\phi(u)_{xx},&&\qquad x\in\Bbb R,\quad t>0,\quad\phi(u)=u^m,\quad m>1,
+\\
+ &u(x,0)=u_0(x),&&\qquad x\in\Bbb R.
+\endalignedat
+\tag 1.1
+$$
+We assume that the initial data $u_0(x)$ has bounded support, that
+$0\leq u_0\leq M$, and that $\phi(u_0)_x\in\bvr$.
+It is well known that a unique solution $u(x,t)$ of (1.1) exists,
+and that $u$ satisfies
+$$
+ 0\leq u\leq M\text{ and }\TV\phi(u(\,\cdot\,,t))_x\leq\TV\phi(u_0)_x.
+\tag 1.2
+$$
+If the data has slightly more regularity, then this too is satisfied
+by the solution. Specifically, if $m$ is no greater than two and
+$u_0$ is Lipschitz continuous, then $u(\,\cdot\,,t)$ is also Lipschitz;
+if $m$ is greater than two and $(u_0^{m-1})_x\in\linfr$, then
+$(u(\,\cdot\,,t)^{m-1})_x\in\linfr$
+(see [3]). (This will follow from results presented here, also.)
+We also use the fact that the solution $u$ is H\"older continuous in $t$.
+
+\subhead 2. $\linfr$ error bounds\endsubhead
+After a simple definition, we state a theorem
+that expresses the error of approximations $u^h$ in
+terms of the weak truncation error $E$.
+\definition{Definition 2.1}\rm A {\it definition}
+is the same as a theorem set in roman
+type. In version 2 of the \AmSTeX\ style file for the SIAM journals,
+definitions are set with their own command.
+\enddefinition
+\proclaim{Theorem 2.1}
+Let $\{u^h\}$ be a family of approximate solutions satisfying
+the following conditions for $0\leq t\leq T${\rm:}
+\roster
+\item For all $x\in\Bbb R$ and positive $t$, $0\leq u^h(x,t)\leq M${\rm;}
+\item Both $u$ and $u^h$ are H\"older--$\alpha$ in $x$
+for some $\alpha\in(0,1\wedge 1/(m-1))${\rm;} $u^h$ is right
+continuous in $t${\rm;}
+and $u^h$ is H\"older continuous in $t$ on
+strips $\Bbb R\times(t^n,t^{n+1})$, with the set $\{t^n\}$ having no
+limit points\/{\rm;} and
+\item There exists a positive function $\omega(h,\epsilon)$ such that\/{\rm:}
+whenever $\{w^\epsilon\}_{0<\epsilon\leq\epsilon_0}$ is a family of functions
+in $\bold X$ for which
+{\roster
+\item"(a)" there is a sequence of positive numbers $\epsilon$ tending
+to zero, such that for these values of
+$\epsilon$, $\|w^\epsilon\|_\infty\leq 1/\epsilon$,
+\item"(b)" for all positive
+$\epsilon$, $\|w_x^\epsilon(\sdot,t)\|_\loner\leq 1/\epsilon^2$, and
+\item"(c)" for all $\epsilon>0$,
+$$
+\sup\Sb
+x\in\Bbb R\\0\leq t_1,t_2\leq T\endSb
+\dfrac{|w^\epsilon(x,t_2)-w^\epsilon(x,t_1)|}{|t_2-t_1|^p}\leq 1/\epsilon^2,
+$$
+where $p$ is some number not exceeding $1$,
+\endroster}%
+then\footnote{This is an obvious ploy, but we need a footnote.}
+ $|E (u^h,w^\epsilon,T)|\leq\omega(h,\epsilon).$
+\item
+This is the fourth item in the outer roster.
+\endroster
+Then, there is a constant $C=C(m,M,T)$ such that
+$$\multline
+\|u-u^h\|_{\infty,\Bbb R\times[0,T]}\leq C\biggl[
+\sup \biggl |\int_\Bbb R(u_0(x)-u^h(x,0)) w(x,0) \,dx\biggr|\\
++\omega(h,\epsilon)+\epsilon^\alpha\biggr],\endmultline
+\tag 2.1
+$$
+where the supremum is taken over all $w\in\bold X$.
+\endproclaim
+
+\demo{Proof}
+We assume first that $Q$ is decreasing and consider the following cases:
+\case{Case\/ {\rm1:}
+$b'\geq 1/2$} We have $P(1/8)\geq\delta>0$ where $\delta$
+depends only on $d$, for otherwise by (3.7) applied to $P$ and $p=\infty$,
+$P$ could not attain the value $1$ at $x=1$. Similarly, for
+$m=(a'+b')/2$, $Q(m)\geq\delta'>0$ for some $\delta'$ depending only on $d$
+since otherwise $Q$ cannot attain the value $1$ at $x=a'$. Hence, for
+$\delta''=\min(\delta,\delta')$,
+$|A(y)|\geq|m-1/8|\geq b'/4\geq\frac18\max(b',1)$ for
+$y\in[0,\delta'']$. On the other hand,
+$|A(y)|\leq \max(b',1)$ for all $y\in[0,1]$, so (4.2) follows for
+all $1\leq p\leq\infty$.
+\endcase
+\case{Case\/ {\rm2:}
+$b'\leq 1/2$} We have $P(3/4)\leq\delta<1$ with $\delta$
+depending only on $d$ for otherwise (3.7) applied to $1-P$ and $p=\infty$
+would show that $P$ could not attain the value $0$ at $x=0$. It follows
+that $|A(y)|\geq 3/4-b'\geq 1/4$, $y\in[\delta,1]$, while $|A(y)|\leq 1$
+for all $y\in[0,1]$. Hence (4.2) follows for
+all $1\leq p\leq\infty$.
+\endcase
+We consider now when $Q$ is increasing. We can assume that $Q$ is not
+a translate of $P$, i.e\., we do not have $P(x)=Q(x+\delta)$ for some $\delta$,
+for then (4.2) follows trivially. In what follows, $C$ and $\delta$
+depend on $d$, and $C$ may depend on $p$. We consider the following cases:
+\case{Case\/ {\rm3:} $a'\geq 1/4$ and $b'\leq 100$}
+From (3.7) for $P$
+and $p=\infty$, it follows that $P(1/8)\geq\delta$ since otherwise $P$ cannot
+attain the value $1$ at $x=1$. Hence $|A(y)|\geq a'-1/8\geq1/8$ on
+$[0,\delta]$. On the other hand $|A(y)|\leq b'$ for all $y\in[0,1]$ and hence
+(4.2) follows for all $1\leq p\leq\infty$.
+\endcase
+Let $z$ be in $\bold X$. Because $E(u,\sdot,\sdot)\equiv0$,
+Equation (1.5) implies that
+$$
+\int_\Bbb R\Delta uz|^T_0dx=\int_0^T\int_\Bbb R
+\Delta u(z_t+\phi[u,u^h]z_{xx})\,dx\,dt-
+E(u^h,z,t),
+\tag 2.2
+$$
+where $\Delta u=u-u^h$ and
+$$
+\phi[u,u^h]=\dfrac{\phi(u)-\phi(u^h)}{u-u^h}.
+$$
+Extend $\phi[u,u^h](\cdot,t)=\phi[u,u^h](\cdot,0)$ for negative $t$, and
+$\phi[u,u^h](\cdot,t)=\phi[u,u^h](\cdot,T)$
+for $t>T$.
+Fix a point $x_0$ and a number $\epsilon>0$. Let $j_\epsilon$
+be a smooth function of $x$ with integral $1$ and support in
+$[-\epsilon,\epsilon]$,
+and let $J_\delta$ be a smooth function of
+$x$ and $t$ with integral $1$ and support in
+$[-\delta,\delta]\times[-\delta,\delta]$; $\delta$ and $\epsilon$ are
+positive numbers to be specified later.
+We choose $z=z^{\epsilon\delta}$ to satisfy
+$$
+\aligned
+ &z_t+(\delta+J_\delta*\phi[u,u^h])z_{xx}=0,\qquad x\in\Bbb R,\;0
+\leq t\leq T,\\
+ &z(x,T)=j_\epsilon(x-x_0).
+\endaligned
+\tag 2.3
+$$
+The conclusion of the theorem now follows from (2.1) and the fact that
+$$
+|j_\epsilon*\Delta u(x_0,t)-\Delta u(x_0,t)|\leq C\epsilon^\alpha,
+$$
+which follows from Assumption 2.

+\centerline{\bf USING THE \AmSTeX\ SIAM STYLE FILE}
+\medskip
+{\eightpt\centerline{BRADLEY J. LUCIER and DOUGLAS N. ARNOLD}}
+\bigskip
+The \AmSTeX\ SIAM style file, amstexsiam.sty, is intended to help
+authors to produce a paper that is typographically acceptable for
+publication in a SIAM journal. Beginning with version 2,
+amstexsiam.sty inputs amsppt.sty and then makes modifications as
+necessary. Version 2 of amstexsiam.sty works with version 2.1 of
+\AmSTeX\ and version 2.1a of amsppt.sty, and should work with latter
+versions. This brief guide assumes familiarity with \AmSTeX\ and
+amsppt, as documented in {\it The Joy of \TeX\ } by Michael Spivak.
+
+Most of the points introduced below are illustrated in the nonsense
+paper {\it A sample paper, with a rather long title, to illustrate the
+\AmSTeX\ SIAM style}.
+
+\heading{Publication information} When the paper has been accepted,
+10 lines similar to these should be place immediately
+after the \v"documentsyle" line:
+\medskip
+\beginverbatim
+\accepted\SINUM
+\firstpageno{10}
+\lastpageno{12}
+\issuevolume{1}
+\issuenumber{2}
+\issuemonth{February}
+\placenumber{002}
+\issueyear{1988}
+\shortauthor{Bradley J. Lucier and Douglas N. Arnold}
+\shorttitle{A Sample Paper}
+\endverbatim
+\medskip\noindent
+The \v"\accepted" macro should be followed by a control sequence taken
+from the following table indicating the specific journal.
+\medskip
+\settabs\+\indent&Acronym\indent&Title&\cr
+\+& \v"\SINUM"&SIAM Journal on Numerical Analysis&\cr
+\+& \v"\SIREV"&SIAM Review&\cr
+\+& \v"\SIMA"&SIAM Journal on Mathematical Analysis&\cr
+\+& \v"\SIMAX"&SIAM Journal on Matrix Analysis and Applications&\cr
+\+& \v"\SICOMP"&SIAM Journal on Computing&\cr
+\+& \v"\SISC"&SIAM Journal on Scientific Computing&\cr
+\+& \v"\SIOPT"&SIAM Journal on Optimization&\cr
+\+& \v"\SIAP"&SIAM Journal on Applied Mathematics&\cr
+\+& \v"\SICON"&SIAM Journal on Control and Optimization&\cr
+\+& \v"\SIDMA"&SIAM Journal on Discrete Mathematics&\cr
+\medskip\noindent
+The next lines give information for the publication data printed at the
+top of the first page of the paper and for the running heads. This
+information consists of the first page number of the article, the last
+page number of the article, the journal name, the issue volume, the
+issue number, the month of appearance, the year of appearance, the
+place of the paper in the issue, the head for even pages (the
+author(s)'s name(s) shortened if necessary to fit on the headline), and
+the head for odd pages (the title shortened if necessary). If the
+\v"\accepted" macro is not present, the publication information will be
+ignored except for \v"\shortauthor" and \v"\shorttitle", which may be
+used for page headers.
+
+\heading{Top matter} The {\it only}\/ constructions allowed between
+\v"\topmatter" and \v"\endtopmatter" are, in order, \v"\title" $\dots$ \v"\endtitle",
+\v"\author" $\dots$ \v"\endauthor", \v"\abstract" $\dots$ \v"\endabstract",
+\v"\keywords" $\dots$ \v"\endkeywords", and
+\v"\subjclass" $\dots$ \v"\endsubjclass". (For special situations,
+\v"\pretitle", \v"\preauthor", \v"\preabstract", \v"\prekeywords",
+\v"\presubjclass", and \v"\prepaper" can also be defined; see {\it The
+Joy of \TeX\/}).
+
+\heading{Title} Use \v"\title" and \v"\endtitle". Type the title in
+all caps. The title may have a footnote (at final publication time
+there will be a footnote indicating when the paper was received). The
+footnote mark should be a bold asterisk obtained with
+\v"\footnote[\boldkey*]{Text of footnote.}". All math should be typed using
+\v"\boldkey" and \v"\boldsymbol" to get bold italic Roman and Greek letters
+and symbols; see {\it The Joy of \TeX\/}.
+
+\heading{Author} Use \v"\author" and \v"\endauthor". Type the author's
+name in all caps. For multiple authors include the word ``and'' in
+lowercase before the name of the last author. For three or more
+authors follow each author's names except the last with a comma. Give
+the affiliation of each author in a footnote attached to the author's
+name (before the following comma, if any). (Do {\it not} use the
+\v"\affil" or \v"\address" macros.) Statements acknowledging support
+should be contained in the same footnote. The order of footnote
+symbols in these footnotes is dagger (\dag\thinspace =\thinspace
+\v"\dag"), double-dagger (\ddag\thinspace =\thinspace \v"\ddag"),
+section-marker (\S\thinspace = \thinspace\v"\S"), paragraph-marker
+(\P\thinspace = \thinspace\v"\P").
+
+\heading{Abstract} Use \v"\abstract" and \v"\endabstract".
+
+\heading{Keywords} Use \v"\keywords" and \v"\endkeywords". Keywords are separated with commas but not followed by any punctuation.
+
+\heading{Subject classifications} Use \v"\subjclass" and
+\v"\endsubjclass". Subject classifications are separated with commas
+but not followed by any punctuation.
+
+\heading{Footnotes} Use \v"\footnote". Except for the topmatter, discussed
+above, use numbered footnotes.
+
+\heading{Headings} Use \v"\subheading" without ending punctuation. The
+argument usually begins with the section number followed by a period
+and then the section name with only the first word capitalized. Very
+long papers could use \v"\heading" and \v"\subheading". If
+\v"\heading" is used, start heading name with a section mark
+(\S\thinspace =\thinspace\v"\S") and the section number followed by a
+period and the section title with the first letter of each major word
+capitalized. All math should be typed using
+\v"\boldkey" and \v"\boldsymbol" to get bold italic Roman and Greek letters
+and symbols; see {\it The Joy of \TeX\/}.
+
+
+\heading{Equation numbers} Use \v"\tag".
+
+\heading{Proclamations} Use \v"\proclaim" $\dots$ \v"\endproclaim"
+for theorems, lemmas, corollaries, claims, propositions, etc. Use
+\v"\demo" $\dots$ \v"\enddemo" for proofs, \v"\remark" $\dots$ \v"\endremark"
+for remarks,
+\v"\definition" $\dots$ \v"\enddefinition" for definitions,
+\v"\example" $\dots$ \v"\endexample" for examples, and \v"\case" $\dots$ \v"\endcase"
+for cases. In each construction the
+opening control sequence (\v"\proclaim", \v"\demo", $\dots$ ) takes
+a single argument with no closing punctuation as in \v"\proclaim{Theorem 2.3}"
+or \v"\demo{Proof}". If remarks, examples, or cases are to be numbered,
+you must explicitly change to roman type for the number:
+\v"\remark{Remark \rom{3}}".
+
+\heading{Punctuation} All vertical punctuation symbols, i.e.,~), (, :, ;,
+?, !, ], and [, and numbers are to be set on roman type, even if in italic
+text (e.g.,~in proclaims or in the headings of demos, remarks, etc.). One
+can do this with, for example, the \v"\rom" macro, as \v"{\it Assume that
+\rom{(1.1)} holds.}" or \v"{\it Fermat's Last Theorem is true \rom(this is new\rom).}", which yield {\it Assume that
+{\rm (1.1)} holds.} and {\it Fermat's Last Theorem is true {\rm(}this is new\/{\rm)}.}
+
+\heading{End-of-proof mark}The symbol signalling the end of a proof
+is an open box, shown at the end of this paragraph. It is obtained
+with \v"\qed". Appropriate white space will be supplied
+automatically.\qed
+
+\heading{Lists and sublists} Use \v"\roster" $\dots$ \v"\endroster".
+Rosters use default labels of the form (1), (2), etc. Subrosters are
+permitted. Each subroster {\it must}\/ be enclosed in a separate pair
+of braces.
+
+\heading{References} Enclose the reference section with \v"\Refs"
+$\dots$ \v"\endRefs". References are set just as described in {\it The
+Joy of \TeX.} Authors' names must be entered as first and possibly
+middle initial, each followed by a period and a space, followed by the
+last name. Only the first letter of the last name is capitalized.
+Use \v"\by" before either \v"\ed" or \v"\eds".
+
+\heading{Figures and tables} There is only rudimentary support for
+figures and tables in the style file. Use
+\v"\topinsert" $\dots$ \v"\endinsert" or
+\v"\midinsert" $\dots$ \v"\endinsert" to surround a figure, including the
+caption at the end as, for example, \v"\botcaption{Fig.~1} This is a
+figure caption.\endcaption". Use \v"\topinsert" $\dots$ \v"\endinsert"
+or \v"\midinsert" $\dots$ \v"\endinsert"to surround the table, including
+the caption at the start as, for example, \v"\topcaption{Table 1}This
+line describes the table\endcaption".
+Place rules above and below column headings and at the
+end of the table using \v"\hbox to \hsize{\hrulefill}".
+
+\heading{Table of contents} No special macros are provided to set
+a table of contents. You can try the macros described in {\it The Joy of
+\TeX\/}. Otherwise, follow these
+guidelines. Switch to eight point type (\v"\eightpoint").
+Center the word ``CONTENTS'' in caps. Capitalize only the first word
+of entries. Runover lines align with the start of entries.
+Place the section number flush left with one em to section title,
+spaced dots from end of entry to page number, and two ems between the
+dots and page number. Leave 18--20 points of vertical space, baseline
+to baseline, to the text above and below.
