A correction adaptive two-grid finite element method for nonselfadjoint or indefinite elliptic problems
Fei Li, Qingguo Hong, Ming Tang +1
We propose, analyze, and numerically validate a correction adaptive two-grid finite element method (CAT-GFEM) for nonselfadjoint or indefinite elliptic problems. In contrast to the…

Iterative two-level algorithm for nonsymmetric or indefinite elliptic problems
Ming Tang, Xiaoqing Xing, Ying Yang +1
In this paper, a new iterative two-level algorithm is presented for solving the finite element discretization for nonsymmetric or indefinite elliptic problems. The iterative two-le…

A modified weak Galerkin method for -elliptic problem
Ming Tang, Liuqiang Zhong, Yingying Xie
In this paper, we design and analysis a modified weak Galerkin (MWG) finite element method for elliptic problem. We first introduce a new discrete w…
