The solution of linear systems of algebraic equations that arise from elliptic finite element problems is considered. A two-level overlapping domain decomposition method that can be viewed as a combination of the additive and multiplicative Schwarz methods is studied. This method combines the advantages of the two methods. It converges faster than the additive Schwarz algorithm and is more parallelizable than the multiplicative Schwarz algorithm, and works for general, not necessarily self…

A family of overlapping Schwarz preconditioned Krylov space iterative methods for solving elliptic boundary value problems with operators that are dominated by the self adjoint second order terms but need not be eitherSelf adjoint or de nite All algorithms discussed in this paper involve two levels of preconditionsing and one of the critical components is a global coarse grid problem.
