摘要
主要考虑了经典椭圆方程的一个混合型间断Galerkin方法的离散格式.给出的稳定项是由单元上的残量决定.并讨论了格式的有界性、稳定性及相容性,给出了在所定义范数下的最优误差估计.
In this paper a mixed discontinuous finite element discretization is considered for Passion equation with Dirichlet boundary condition. The boundedness,stability and consistency are presented. And the basic error estimate is obtained with respect to the defined norm.
