(TU Delft Numerical Analysis; University of Tabriz; Research Department of Computational Algorithms and Mathematical Models) Vuik, Cornelis (TU Delft Delft Institute of Applied Mathematics) Date 2022 Abstract In this article, a parameterized extended shift-splitting (PESS) method and its induced preconditioner are given for solving nonsingular and nonsymmetric saddle point problems with nonsymmetric positive definite (1,1) part. The convergence analysis of the (Formula presented.) iteration method is discussed. The distribution of eigenvalues of the preconditioned matrix is provided. A number of experiments are given to verify the efficiency of the (Formula presented.) method for solving nonsymmetric saddle-point problems.
