Abstract:

The aim of this paper is to study the higher order accuracy analysis of fully discrete Galerkin approximations to parabolic equations by biquadratic element under anisotropic meshes. Through the integral identity techniques and some novel approaches the superclose results are obtained.

Key words: High accuracy, Parabolic equation, Biquadratic element, Anisotropic meshes
