Description	A general framework for constructing preconditioners for 2 x 2 block matrices is presented, and eigenvalue bounds of the preconditioned matrices are derived The results are applied both for positive-definite problems and for saddle point matrices of regularized forms. Eigenvalues and minimal polynomials for certain limit cases are derived A domain decomposition method, with overlap, is used to solve the pivot block of the regularized matrix. Special attention is paid to problems with heterogeneous coefficients Copyright (C) 2010 John Wiley & Sons, Ltd.
