Preconditioners for Generalized Saddle-point Problems Preconditioners for Generalized Saddle-point Problems *
We examine block-diagonal preconditioners and efficient variants of indefinite preconditioners for block two-by-two generalized saddle-point problems. We consider the general, nonsymmetric, nonsingular case. In particular, the (1,2) block need not equal the transposed (2,1) block. Our preconditioners arise from computationally efficient splittings of the (1,1) block. We provide analyses for the...
متن کاملOn the generalized shift-splitting preconditioner for saddle point problems
In this paper, the generalized shift-splitting preconditioner is implemented for saddle point problems with symmetric positive definite (1,1)-block and symmetric positive semidefinite (2,2)-block. The proposed preconditioner is extracted form a stationary iterative method which is unconditionally convergent. Moreover, a relaxed version of the proposed preconditioner is presented and some proper...

Wathen Mixed nite element formulations give rise to large, sparse, blo k linear systems of equations the solution of whi h is often sought via a pre onditioned iterative te hnique. In this work we present a general analysis of blo kpre onditioners based on the stability onditions inherited from the formulation of the nite...
متن کاملPreconditioners for Generalized Saddle-Point Problems
We propose and examine block-diagonal preconditioners and variants of indefinite preconditioners for block two-by-two generalized saddle-point problems. That is, we consider the nonsymmetric, nonsingular case where the (2,2) block is small in norm, and we are particularly concerned with the case where the (1,2) block is different from the transposed (2,1) block. We provide theoretical and exper...
متن کاملSubstructure Preconditioners for Elliptic Saddle Point Problems
Domain decomposition preconditioners for the linear systems arising from mixed finite element discretizations of second-order elliptic boundary value problems are proposed. The preconditioners are based on subproblems with either Neumann or Dirichlet boundary conditions on the interior boundary. The preconditioned systems have the same structure as the nonpreconditioned systems. In particular, ...
