Shifted skew-symmetric/skew-symmetric splitting method and its application to generalized saddle point problems

摘要

We present a shifted skew-symmetric/skew-symmetric splitting method for solving the shifted skew-symmetric system arisen from implementation of the symmetric/skew-symmetric splitting preconditioner within a Krylov subspace method like GMRES for solving generalized saddle point problems. Numerical results are given to show the efficiency of the method. (C) 2019 Elsevier Ltd. All rights reserved.
