A Sufficient Conditions for Nonsingular Block H-Matrices
First, we introduce the concept of a kind of block diagonally dominant matrices, and then on the basis of original pointwise H-matrices, we discuss block diagonally dominant matrices by using block matrix technology and certifying structurally. Finally, two simple criteria for nonsingular block H-matrices are given entirely. Result obtained improves results in the known corresponding references.
