Convergence Analysis of the Splitting-Based Iterative Method for Solving Generalized Saddle Point Problems

In this paper, we present a parameterized inexact Uzawa type method for solving a class of large sparse generalized saddle point problems, and analyze its convergence using a different approach from those utilized in the existing literature. Some numerical results are given to illustrate the effecti...

Zusammenfassung:In this paper, we present a parameterized inexact Uzawa type method for solving a class of large sparse generalized saddle point problems, and analyze its convergence using a different approach from those utilized in the existing literature. Some numerical results are given to illustrate the effectiveness of the proposed method.
