摘要：

It is well-known that the Schur complements of strictly diagonally dominant matrices are strictly diagonally matrices [1], the same are true of block diagonally dominant matrix and H-matrices [2, 3]. In this paper, these results are extended to the weak block diagonally dominant matrices and weak block H-matrices, that is, it are shown that the Schur complements of weak block diagonally dominant matrices are weak block diagonally dominant matrices and so are the Schur complements of a weak block H-matrices.
