关于L-弱和M-弱紧算子类

On the class of order L-weakly and order M-weakly compact operators

Driss Lhaimer, Khalid Bouras, Mohammed Moussa

摘要:

本文引入并研究了序L-弱和序M-弱紧算子的新概念。作为推论,我们得到了具有序连续范数的巴拿赫格和具有序连续范数的拓扑格的一些刻画。证明了如果$T : E \longrightarrow F$是两个巴拿赫格之间的算子,则T是阶M-弱紧的当且仅当它的伴随T'是阶L-弱紧的。证明了若其伴随T'是M-弱紧的,则T是L-弱紧的.并得到了一些相关结果。

英文摘要:

In this paper, we introduce and study new concepts of order L-weakly and order M-weakly compact operators. As consequences, we obtain some characterizations of Banach lattices with order continuous norms or whose topological duals have order continuous norms. It is proved that if $T : E \longrightarrow F$ is an operator between two Banach lattices, then T is order M-weakly compact if and only if its adjoint T' is order L-weakly compact. Also, we show that if its adjoint T' is order M-weakly compact, then T is order L-weakly compact. Some related results are also obtained.
