Resumen de Semi-convergence of the generalized local HSS method for singular saddle point problems

Shu Xin Miao, Yang Cao

• Recently, Zhu [Appl. Math. Comput., 218 (2012), 8816-8824] considered the generalized local HSS (GLHSS) method for solving nonsingular saddle point problems and studied its convergence. In this paper, we prove the semi-convergence of the GLHSS method when it is applied to solve the singular saddle point problems.
