Constraint preconditioning for indefinite linear systems
The problem of finding good preconditioners for the numerical solution of indefinite linear systems is considered. Special emphasis is put on preconditioners that have a 2 × 2 block structure and that incorporate the (1, 2) and (2, 1) blocks of the original matrix. Results concerning the spectrum an...
