| Abstract: | In this paper, some properties of irreducible diagonally dominant N0- matrices are discussed on the basis of some properties of a strictly diagonally dominant matrix. At the same time, an estimation of the smallest eigenvalue of No_ matrix and inverse N0- matrix in module is proved. |
