Journal of Numerical mathematics 2005年 第3期13卷 157-169页
作者: Bacuta, C. Chen, J. Huang, Y. Xu, J. Zikatanov, L. Mathematical Sciences University of Delaware Newark DE 19716 School of Mathematics and Computer Science Nanjing Normal University Nanjing 210097 China Institute for Computational and Applied Mathematics Department of Mathematics Xiangtan University 411105 China Department of Mathematics Pennsylvania State University University Park PA 16802
We consider the Stokes problem on a plane polygonal domain Ω ⊂ 2. We propose a finite element method for overlapping or nonmatching grids for the Stokes problem based on the partition of unity method. We prove that t... 详细信息
