local multilevel methodS FOR SECOND-ORDER ELLIPTIC PROBLEMS WITH HIGHLY DISCONTINUOUS COEFFICIENTS
收藏 引用
Journal of Computational Mathematics 2012年 第3期30卷 223-248页
作者: Huangxin Chen Xuejun Xu Weiying Zheng School of Mathematical Sciences Xiamen UniversityXiamen 361005China LSEC ICMSECAcademy of Mathematics and System SciencesChinese Academy of SciencesBeijing 100190China
In this paper, local multiplicative and additive multilevel methods on adaptively refined meshes are considered for second-order elliptic problems with highly discontinuous coeffi- cients. For the multilevel-precondit... 详细信息

A local multilevel PRECONDITIONER FOR THE ADAPTIVE MORTAR FINITE ELEMENT method
收藏 引用
Journal of Computational Mathematics 2013年 第5期31卷 532-548页
作者: Feng Wang Jinru Chen Jiangsu Key Laboratory for NSLSCS School of Mathematical Sciences Nanjing Normal University Nanjing 210023 China
In this paper, we propose a local multilevel preconditioner for the mortar finite element approximations of the elliptic problems. With some mesh assumptions on the interface, we prove that the condition number of the... 详细信息
