A new error estimate on uniform norm of schwarz algorithm for elliptic quasi-variational inequalities with nonlinear source terms
收藏 引用
JOURNAL OF INEQUALITIES AND APPLICATIONS 2018年 第1期2018卷 1-13页
作者: Mehri, Allaoua Saadi, Samira Univ May 8th 1945 Dept Math Lab LANOS Guelma Algeria Univ Badji Mokhtar Annaba Dept Math Lab LANOS Annaba Algeria
The schwarz algorithm for a class of elliptic quasi-variational inequalities with nonlinear source terms is studied in this work. The authors prove a new error estimate in uniform norm, making use of a stability prope... 详细信息

IMA JOURNAL OF NUMERICAL ANALYSIS 2010年 第4期30卷 1062-1100页
作者: Boyer, Franck Hubert, Florence Krell, Stella Univ Paul Cezanne Lab Anal Topol & Probabilites FST St Jerome F-13397 Marseille 20 France
We propose a nonoverlapping schwarz algorithm for solving 'discrete duality finite-volume' (DDFV) schemes on general meshes. In order to handle this problem the first step is to propose and study a convenient ... 详细信息
