Banach空间算子闭值域区域的正则划分

T-regular points of Closed-range of Banach Space Operators

本文讨论空间算子闭值域区域和-正则点和-奇异点，引入算子的约化最小模函数，用它刻划算子闭值域区域，得到与的若干结构表示定理．

In the paper, we consider T-regular points of Banach space operators. We discuss the set of regular points and singular points in closed-range of Banach space operator T with the reduced minimum modulus function . And some result about structures of and are given.
