摘要

给定作用于可分离巴拿赫空间上的有界线性算子 TT,且满足 (Mp)(M_p) 条件,我们证明了该算子所有最大化序列的弱聚点中,最小范数与最大范数只能取值 0011。由这些极端范数值所衍生的三个有界线性算子类别,与考虑范数吸收性及其基本范数是否等于范数的划分相吻合。

6 pages, 1 figure, In the proof Proposition 3.2 (now Proposition 3.4), it was claimed MV is finite dimensional. This is unclear, but it is compact. I was informed about an article by Sreejith Siju, which has been added and given credit where credit is due (e.g. in the proof of the main theorem)
