摘要
本文给出了所有弱紧算子 ,强紧算子 ,Mackey紧算子 ,构成无穷矩阵拓扑下相同紧集的特征的刻画 .
In this paper,we show that all weak compact operators,all Mackey compact operators and all strong compact operators in a class of infinite matrix topological algebras are ideals.We also discuss the charcteristics of (λ,μ)under two special topologies have the same compact sets.
