| Abstract: | In l-8], the authors give some necessary and sufficient conditions for verifying generalized strictly diagonally dominant matrices. In this paper, we further discusse the relations about the three kinds of generalized strictly diagonally dominant matrices, and prove the important resultsG G1 G2. IG IG1 IG2. |
