论文摘要
在本文中,我们介绍并研究了订单的新概念,并订购了紧凑的操作员。结果,我们获得了具有连续规范的Banach晶格的一些特征,或者其拓扑二元组具有连续规范。事实证明,如果$ t:e \ longrightArrow f $是两个Banach晶格之间的操作员,那么当它的伴随t'是订单的订单时,t是紧凑的,t是紧凑的。另外,我们表明,如果它的伴随t'是序列的紧凑,则t是顺序紧凑。还获得了一些相关的结果。
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.
