  • Abstract

In this paper, we investigate the superconvergence property of a timedependent nonlinear Schrodinger equation with the bilinear finite element method on the rectangular mesh. We prove the superclose error estimate in H1-norm with order O(h2) between the approximated solution and the elliptic projection of the exact solution. Moreover, we obtain the global superconvergence result in H1-norm with order O(h2) by the interpolation post-processing operator.
