Schr(o)dinger方程一个新的H1-Galerkin非协调混合限元方法
An H1-Galerkin nonconforming mixed finite element method of Schr(o)dinger equation
摘要
Abstract
In this paper, a new Hl -Galerkin nonconforming mixed finite element method of Schrodinger equation is proposed. It needn't satisfy LBB consistency condition. Moreover, without the traditional Ritz projection, and by the orthogonality of interpolation operator, the optimal error estimates and some superclose results are obtained. Furthermore, the global superconvergence is derived through constructing the interpolated post-processing operator.关键词
