Abstract:

 By means of the fact that irreducibly diagonally dominant matrices and diagonally dominant matrix with a chain of non\|zero elements are nonsingular H-matrices, two criteria for nonsingular H-matrices were presented, which improves related results in the literature.

Key words: nonsingular H-matrix, diagonally dominant matrix, irreducibly diagonally dominant matrix
