name functan category Package shortdesc macros for functional analysis and PDE theory longdesc This package provides a convenient and coherent way to deal with longdesc name of functional spaces (mainly Sobolev spaces) in functional longdesc analysis and PDE theory. It also provides a set of macros for longdesc dealing with norms, scalar products and convergence with some longdesc object oriented flavor (it gives the possibility to override the longdesc standard behavior of norms, ...).
