Abstract

In this paper, we shall study the initial boundary value problem of Schrodinger equation. The second order gradient superconvergence estimates for the problem are obtained solving by linear finite elements.

Key words: Finite element; superconvergence estimates; interpolation; Schrodinger equation.
