Block LU Preconditioners for Symmetric and Nonsymmetric Saddle Point Problems
In this paper, a block LU preconditioner for saddle point problems is presented. The main diierence between the approach presented here and that of other studies is that an explicit, accurate approximation of the Schur complement matrix is eeciently computed. This is used to compute a preconditioner to the Schur complement matrix that in turn deenes a preconditioner for a global iteration. The ...
متن کاملPreconditioners 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...

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...
