Generalized block triangular preconditioner for saddle point systems

摘要：

　　In this paper,based on the preconditioner for saddle point systems in Benzi and Liu M.Benzi,J.Liu,Block preconditioning for saddle point systems with indefinite (1,1) block,International Journal of Computer Mathematics,84(8) (2007) 1117-1129,we present the generalized block preconditioner for generalized saddle point systems,which uses some more parameters and is a generalization of Benzi and Lius block preconditioner.Moreover,spectral properties of our generalized block triangular preconditioner are given.
