摘要
本文讨论了全非负阵与其逆矩阵的关系,改进了关于全非负矩阵的Hadamard-Fischer不等式的几个近期结果.
In this paper, we discussed reationship between totally nonnegative matrices and its inverse matrix. Further, we obtained some improvement of the Hadamard-Fischer inequality for totally nonnegative Matrices. They improved present some cesults.
