Combination preconditioning of saddle point systems for positive definiteness

Combination preconditioning of saddle point systems for positive definiteness

Čájet eará veršuvnnaid (2)

Amongst recent contributions to preconditioning methods for saddle point systems, standard iterative methods in nonstandard inner products have been usefully employed. Krzyzanowski (Numer. Linear Algebra Appl. 2011; 18:123–140) identified a two-parameter family of preconditioners in this context and...
