关于次正定矩阵行列式不等式的注记

Note on Determinant Inequalities of Metapositive Definite Matrix

首先指出了文 [1]中定理 7的错误 ,给出一个行列式不等式 ,改正了文 [1]的错误且推广了文 [3]的结果 ,进而 ,又给出了次正定矩阵行列式的其它一些不等式 。

This paper points out a mistake in paper,and then presents a determinant inequality of metapositive definite matrix which corrects the mistake in paper,and extends the results of paper,finally,gives out several determinant inequalities of metapositive definite matrix and extends some results of determinant inequalities of positive definite matrix to metapositive definite matrix.
