摘要
1对1)A、B是两个任意同阶的Hermite矩阵;2)A、B是两个同阶的正规矩阵;3)A、B是两个任意同阶的复矩阵这三种情形分别给出了乘积AB的特征值的取值范围,其结果是最优的。2讨论了两个Hermite矩阵A、B的Kro-necker积A×B及Hadamard积AB的特征值的取值范围;3给出了Her-mite矩阵的特征值及一般复矩阵谱半径的两个新的估计式,其结果优于Frobe-nius谱半径估计。
In this paper:1 When A and B are two arbitrary same order Hermitian matrices or same order nor-mal matrices,or arbitrary same order complex matrices. The estimations of the eigenvaluesof product for A and B is given.2 The estimation of the eigenvalues of Kronecker product and Hadamard product fortwo Hermitian matrices is given.3 Two new estimations of the eigenvalues of Hermitian matrices and the spectralrdius of complex matrices are given.
