The authors are concerned with the verification of numerical solutions of symmetric saddle point linear systems. Their method is based on results of an algebraic analysis of a block diagonal preconditioner. They extend in this way some previous similar results. Numerical experiments and comparisons with previous algorithms are also presented.
