Abstract

Abstract. In this paper which is motivated by computation on parallel machine, we show that the superconvergence results of the finite element method(FEM) with Lagrange mul- tipliers based on domain decomposition method (DDM) with nonmatching grids can be carried over to parabolic problems.

Key words

Non-conforming domain decomposition method / Lagrange multipliers / parabolicproblem / superconvergenc
