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.
