Analysis of PDEs 2018-07-24 v1

Abstract

In this article we derive a priori error estimates for the hphp-version of the mortar finite element method for parabolic initial-boundary value problems. Both semidiscrete and fully discrete methods are analysed in L2L^2- and H1H^1-norms. The superconvergence results for the solution of the semidiscrete problem are studied in an eqivalent negative norm, with an extra regularity assumption. Numerical experiments are conducted to validate the theoretical findings.
