A domain decomposition algorithm for general covolume methods for elliptic problems

In this paper we introduce and analyze a two-level Schwarz additive domain decomposition method used as a preconditioner of a GMRES algorithm for solving unsymmetric systems arising from the finite volume element or covolume methods for elliptic problems...
