A New Preconditioner with Two Variable Relaxation Parameters for Saddle Point Linear Systems with Hi
[期刊论文] 作者：Yuping Zeng,Chenliang Li,
来源：美国计算数学期刊(英文) 年份：2011
In this paper, we provide new preconditioner for saddle point linear systems with (1,1) blocks that have a high nullity. The preconditioner is block triangular...

A POSTERIORI ERROR ESTIMATES FOR A MODIFIED WEAK GALERKIN FINITE ELEMENT APPROXIMATION OF SECOND ORD
[期刊论文] 作者：Yuping Zeng,Feng Wang,Zhifeng Weng,Hanzhang Hu,
来源：计算数学（英文版） 年份：2021
In this paper,we derive a residual based a posteriori error estimator for a modified weak Galerkin formulation of second order elliptic problems.We prove that the error estimator used for interior penalty discontinuous Galerkin methods stil......
