摘要：

Two types of (modified) incomplete block factorization methods are considered, and the existence and convergence of the related splittings are established for H-matrices. This is done by studying in parallel the similar preconditioner for an M-matrix A which satisfies A less-than-or-equal-to M(A). We show also for the M-matrix case somewhat more general results for the type of preconditioners considered than previously found in the literature.
