本文旨在讨论矩阵乘积核心逆在0点特征投影的一些性质,研究具有相同核心逆特征投影的两矩阵之间的关系,给出相同核心逆特征投影条件下核心逆的扰动界。
The aim of this paper is to disscuse some characteristics of the core inverse of matrix multiplication corressponding to point 0 eigenprojection.It studies the relationship between two matrixes with the same characteristic eigenprojection of core inverse and gives the pertubation of the core inverse in the case of same eigenprojection.
