摘要
从空间拓扑直和分解角度研究Hilbert空间中有界线性算子伪核逆的扰动问题,给出伪核逆具有最简表示的充要条件和稳定扰动下伪核逆的表达式.
Abstract
From the perspective of the decomposition of the topological direct sum,the perturbation problem of the pseudo core inverse of bounded linear operators in Hilbert space is studied.Some necessary and sufficient conditions for the pseudo core inverse to have the simplest expression and the expression of the pseudo core inverse under the stable perturbation are given.
