LF拓扑空间的S—可列闭空间

S-countably closed space in LF topological space

给出了在LF拓扑空间中(LX,δ)为S-可列闭空间,可列H(i)空间,可列紧空间,S-可列紧空间,强S-可列闭空间等概念;并证明了在LF拓扑空间中S-可列闭空间的性质。

In LF topological space,the concepts of（L^X,δ）, s S-countable closed space, countable H （i） space,countable tight space,S-countable tight space,and strong S-countable closed space are provided,and the attribute of S-countable closed space in LF topological space is proved.
