摘要
本文在乘法扰动下研究了加权极分解的广义非负极因子与广义正极因子的扰动界,同时,作为特殊情形,也获得了广义极分解与极分解的非负极因子与正极因子的乘法扰动界.
In this paper,we study the perturbation bounds for the generalized nonnegative and positive polar factors of weighted polar decomposition under multiplicative perturbation. Moreover,as the special cases,the corresponding perturbation bounds for nonnegative and positive polar factors are also presented.
