GLHSS Method for Singular Saddle Point Problems
Yougui Wei · 2013
For large sparse saddle point problems, Zhu studied a generalized local Hermitian and skew-Hermitian splitting (GLHSS) method for the non-Hermitian saddle problem (see M.Z.Zhu, A generalized local Hermitian and skew-Hermitian splitting iteration methods for the non-Hermitian saddle point problems, J. Comput. Appl. Math., 218 (2012) 8816-8824). In this paper, we present GLHSS method for singular saddle point problems and derive conditions for guaranteeing the semiconvergence.
