| Abstract: | In this paper, we introduce the concept of weak irreducible diagonal dominant matrix with nonzero element chain according circuit, discuss equivalent conditions of M-matrices, and give two equivalent characterizations of M-matrices which improve and generalize the corresponding results in [1] , [2] , [5] . [9]. |
| Keywords: | M-matrices Weakly irreducible diagonal dominance G-function Directed graph |
