Abstract
In this paper spectral properties and computational performance of a generalized block triangular preconditioner for symmetric saddle point problems are discussed in detail We will provide estimates for the region containing both the nonreal and the real eigenvalues and generalize the results of Simoncini Appl Numer Math 4963–80 2004 and Cao Appl Numer Math 57899–910 2007 Finally numerical experiments of the model Stokes problem are reportedThis research was supported by 973 Programs 2008CB317110 NSFC 10771030 the Scientific and Technological Key Project of the Chinese Education Ministry 107098 the PhD Programs Fund of Chinese Universities 20070614001 Sichuan Province Project for Applied Basic Research 2008JY0052 and the Project for Academic Leader and Group of UESTC
