摘要: 利用α对角占优矩阵理论, 证明了非奇异H-矩阵的一些新的充分条件, 从而拓展了非奇异H-矩阵的判定准则. 

关键词: 非奇异H-矩阵, α对角占优矩阵, 非零元素链

Abstract: Using α diagonally dominant matrix, we proved some new sufficient conditions to judge nonsingular H-matrix and thus we extended the criteria of nonsingular H-matrix.

Key words: nonsingular H-matrix, α diagonally dominant matrix, chain of nonzero elements
