摘要
基于半平面上的自然边界归化理论,给出了一类带凹槽的半无界区域上椭圆型方程边值问题的重叠型区域分解算法,并证明了该算法的几何收敛性,数值例子表明了算法的有效性.
Based on the theory of natural boundary reduction, overlapping domain decomposition method is applied to elliptic boundary value problems over a kind of unbounded half plane with a cave, It is proved that the convergence rate of the algorithm is geometrical. The numerical example shows that the algorithm is effective.
