自反Banach空间算子闭值域的若干性质

SOME PORERY OF CLOSED-RANG OF REFLEXIVE BANACH SPACE OPERATORS

本文讨论自反 Banach空间算子 T-正则点 ,证明了 T及其共轭算子 T* 在闭值域区域上的 T-正则点集的关系 ,ρr D( T)与 ρs D( T)

In the paper,we consider T-regular points of Banach space operators.We give the relation of the set of regular point in closed-range of Banach space operator T and in its adjoint operator T *.And some result about structures of ρr D(T) and ρs D(T) are given.
