厄米特矩阵和与积的特征值不等式

Some Inequalities for Eigenvalues of Sum and Product of Hermitian Matrices

本文讨论了ｋ（≥２）个厄米特矩阵之和的特征值不等式，ｋ（≥２）个厄米特正定矩阵之和的特征值不等式，这些结果推广与改进了［１］，［４］的相应结果．

In this paper,we discuss some inequalities for eigenvalues of sum and product of k(≥2) hermitian matrices,these results generalize and improve corresponding results of 1 and 4 .
