基于 PSS 迭代分裂的广义鞍点问题求解

摘要

We presented a generalized Uzawa iterative method for solving the generalized saddle-point problems based on the positive definite and skew-Hermitian splitting (PSS)iterative method,that is, the modified local PSS iterative method,and analyzed the convergence of the method.Numerical results are illustrated to show that the effectiveness of the new algorithm.%基于正定和反 Hermite 分裂(PSS)迭代技术，给出求解广义鞍点问题的一种广义Uzawa迭代法———修正局部 PSS 迭代算法，分析了该方法的收敛性，并用数值算例验证了新算法的有效性。
