Superconvergence of Piecewise Linear Semi-Discretizations for Parabolic Equatio...
Description
In this paper we study the convergence properties of semi-discrete approximations for parabolic problems defined on two dimensional polygonal domains. These approximations are constructed using a nonstandard piecewise linear finite element method based on nonuniform triangulations of the domain and considering a variational formulation with a sesquilinear form which can be no strongly coercive. In order to increase accuracy a post-process procedure is studied. http://dx.doi.org/10.1007/s00021-005-0153-y
