摘要
利用强半开集定义了强S-Lindelf可数性的概念,讨论了其基本性质.证明了强S-Lindelf性对强半闭子集是遗传的,具有强半同胚不变性等,并给出了强S-Lindelf空间的一些应用.
The concepts of strong S-Lindelof Space are defined and some basic properties are characterized. It is proved that the strong S-Lindelof space is strong semi-closed heriditary and has strong semi-homomorphic invariablility, etc. And some applications of strong S-Lindelof space are given.
