摘要
借助 α- ω聚点与 α-聚点概念给出可数强 F紧集的两个刻画定理 ,进而讨论可数强 F紧集在 L值 Zadeh型函数下的逆不变性 ,证明了可数强 F紧集与强 F紧集的乘积是可数强 F紧的。
In this paper,we present characterizations of countably strong fuzzy compact set by means of the concepts of α ω accumulation point and α accumulation point. We discuss inverse invarant property of countably strong fuzzy compact set under L Zadeh type function. We prove that product of a strong fuzzy compact set and a countably strong fuzzy compact set is countably strong fuzzy compact set.
