This paper proves the convergence of some generalized Schwarz algorithms for solving the obstacle problems with a T-monotone operator. Numerical results show that the generalized Sehwarz algorithms converge faster than the classical Schwarz algorithms.

โฆ Synopsis
In this paper, we present so-called generalized additive and multiplicative Schwarz algorithms for solving the discretization problems of obstacle problems with a self-adjoint elliptic operator. We establish convergence theorems for the proposed algorithms. Numerical tests show that a faster convergence rate can be obtained by choosing suitable parameters in the algorithms.
