As is well known, the generalized inverse, Moore–Penrose inverse and group inverse are not continuous, i.e. for and , a linear bounded operator T has a θ-inverse , the perturbed operator is not necessary θ-invertible and even if it is θ-invertible, may not be true. In this paper, we prove that is θ-invertible and its θ-inverse has the simplest possible expression, which satisfies . Thus, we have found a continuous orbit for the generalized inverse, Moore–Penrose inverse and group inverse.

广义逆,摩尔-彭罗斯逆和群逆的连续轨道
众所周知,广义逆,摩尔-彭罗斯逆和群逆不是连续的,即对于 和 ,线性有界算子T具有θ逆,受干扰的运算符 不必是θ可逆的,即使它是θ可逆的,可能不是真的。在本文中,我们证明是θ-可逆且θ-逆 具有最简单的表达式,可以满足 。因此,我们发现了广义逆,摩尔-彭罗斯逆和群逆的连续轨道。
