摘要：
In this paper, the class of K-0-matrices, which includes positive definite matrices, totally positive matrices, M-matrices and inverse M-matrices, is first introduced and the refinements of Fischer's inequality and Hadamard's inequality for K-0-matrices are obtained. Some previous well-known results for totally nonnegative matrices can be regarded as the special case of this paper.
