Spectral Properties of the Iteration Matrix of the HSS Method for Saddle Point Problem
Cui Qun-fa, Cui-Xia Li, Shi-Liang Wu · Mathematical Problems in Engineering · 2014
We discuss spectral properties of the iteration matrix of the HSS method for saddle point problems and derive estimates for the region containing both the nonreal and real eigenvalues of the iteration matrix of the HSS method for saddle point problems.
