Shu-Xin Miao: The semi-convergence of GSI method for singular saddle point problems, p.93-100

Abstract:

Recently, Miao and Wang considered the GSI method for solving nonsingular saddle point problems and studied the convergence of the GSI method. In this paper, we prove the semi-convergence of the GSI method when it is applied to solve the singular saddle point problems.

Key Words: GSI method, Singular saddle point problem, Semi-convergence, Iterative method.
