KW - Nonsymmetric saddle point problems, fast shift-splitting, convergence, semi-convergence.
AB - <p style="text-align: justify;">Based on the shift-splitting technique and the idea of Hermitian and skew-Hermitian
splitting, a fast shift-splitting iteration method is proposed for solving nonsingular
and singular nonsymmetric saddle point problems in this paper. Convergence
and semi-convergence of the proposed iteration method for nonsingular and singular
cases are carefully studied, respectively. Numerical experiments are implemented to
demonstrate the feasibility and effectiveness of the proposed method.</p>
