A Non-overlapping Domain Decomposition Algorithm for Elliptic Boundary Value Problems with Infinite Concave Angle Domain

研究无穷凹角型区域椭圆边值问题的一种非重叠型区域分解算法.构造其算法并讨论相应的离散化问题的收敛性,最后给出了数值例子以说明方法的有效性.

In this paper,we investigate a nonoverlapping domain decomposition algorithm for elliptic boundary value problems with infinite concave angle domain. The algorithm is constructed,and the convergence of its discrete problems is discussed. Finally,some numerical examples are presented to show that our method is effective.
