On iterative methods and implicit-factorization preconditioners for regularized saddle-point systems

On iterative methods and implicit-factorization preconditioners for regularized saddle-point systems

We consider conjugate-gradient like methods for solving block symmetric indefinite linear systems that arise from saddle point problems or, in particular, regularizations thereof. Such methods require preconditioners that preserve certain sub-blocks from the original systems but allow considerable f...
