Semi-Convergence Of The Local Hermitian And Skew-Hermitian Splitting Iteration Methods For Singular Generalized Saddle Point Problems
Jianlei Li, Qingnian Zhang, Shi-Liang Wu · 2011
In this paper, the local Hermitian and skew-Hermitian splitting (LHSS) iteration method and the modified LHSS (MLHSS) iteration method for solving singular generalized saddle point problems were investigated. When A is non-Hermitian positive definite and the Hermitian part of A is dominant, the semiconvergence conditions are given, which generalize some results of Jiang and Cao for the nonsingular generalized saddle point problems to the singular generalized saddle point problems.
