ON THE PSEUDO-BOUNDARY RELAXATION OF THE SCHWARZ ALTERNATING METHOD
关于Schwarz交替法的拟边界松弛方法

One of the techniques for accelerating the convergence of the Schwarz alternating me-thod is the pseudo-boundary relaxation. Evans, Kang et al. proposed a pseudo-boundary re-laxation procedure and analysed its convergence for model problems1]. In this paper a morenatural pseudo-boundary relaxation. procedure s proposed and it is shown to have smaller con-vergence factor than the method proposed in 1] for general self-adjoint ellipic problems.
