Two-grid algorithm for two-dimensional linear Schrödinger equation by the mixed finite element method

In this paper, we propose a new two-grid algorithm for solving two-dimensional Schrödinger equation in semi-discrete and fully discrete mixed finite element scheme, respectively. With this algorithm, the solution of the Schrödinger equation on a fine grid can be reduced to the original problem on a...
