A One-level Additive Schwarz Preconditioner for a Discontinuous Petrov-Galerkin Method (1212.2645v1)
Published 11 Dec 2012 in math.NA
Abstract: Discontinuous Petrov-Galerkin (DPG) methods are new discontinuous Galerkin methods with interesting properties. In this article we consider a domain decomposition preconditioner for a DPG method for the Poisson problem.
