| Abstract: | Li Yao-tang and Li Ji-cheng have estimated the lower bounds of two H-matrix product determinants recently. With the application of the new conclusion and method we obtained from the Oppenheim inequation of M-matrix Hadamard Product, we have generalized and improved Li Yao-tang and Li Ji-cheng's corresponding conclusion. |
