| Abstract: | According to irreducible diagonal dominance, nonzero chains-type diagonal dominance and generalized diagonal dominance etc. By use of the concept of comparison matrix, criteria for generalized diagonally dominant matrices are investigated. New criteria are presented. Some results in literature are generalized. |

| Keywords: | nonsingular H-matrix diagonal dominance matrix nonzero elements chain irreducible matrix |
