巴拿赫格中无界绝对weak convergence的一些性质

Some properties on the unbounded absolute weak convergence in Banach lattices

Aziz Elbour

摘要:

本文进一步研究了$uaw$ -收敛(分别为$un$ -收敛)和弱收敛。更准确地说,我们刻画了巴拿赫格上的每个弱零序列是$uaw$ -null的。另外,我们还刻画了序连续巴拿赫格,在此格下,每个范数有界的$un$ -空网(分别为.序列)是弱空的。因此,我们研究了序列$uaw$ -紧算子与弱紧算子之间的关系。证明了从巴拿赫格$E$到非零Banach空间$X$的连续算子是无界连续的当且仅当$E^{\prime }$是序连续的.最后,利用$uaw$ -收敛序列给出了$b$ -弱紧算子的一个新的刻画.

英文摘要:

In this paper, we investigate more about relationship between $uaw$ -convergence (resp. $un$-convergence) and the weak convergence. More precisely, we characterize Banach lattices on which every weak null sequence is $uaw$-null. Also, we characterize order continuous Banach lattices under which every norm bounded $un$-null net (resp. sequence) is weakly null. As a consequence, we study relationship between sequentially $uaw$-compact operators and weakly compact operators. Also, it is proved that every continuous operator, from a Banach lattice $E$ into a non-zero Banach space $X$, is unbounded continuous if and only if $E^{\prime }$ is order continuous. Finally, we give a new characterization of $b$-weakly compact operators using the $uaw$-convergence sequences.
