Deflated Krylov Subspace Methods for Nearly Singular Linear Systems

Abstract

This paper concerns the use of Krylov subspace methods for the solution of nearly singular nonsymmetric linear systems. We show that the Incomplete Orthogonalization Methods (IOM) in conjunction with certain deflation techniques of Stewart and Chan can be used to solve large non-symmetric linear systems which are nearly singular.
