关于A的若干谱性质

On the Spectral Properities of the Matrix A

根据共轭相似的定义和性质对A的性质作进一步的研究,特别是A的负特征值的分布的结论,将对研究共轭特征值的分布和正规矩阵的特征值分布有重大意义.

By using the theorems and the results in the references of [1],[4],[5], we further study the spectral properities of the matrix AA^-, which will be important for the study of coneigvenvalues and the eigvenvalues of normal matrix.
