3) LF-r closed set
LF-r闭集
1.
The concepts of r remote neighborhood family and r- remote neighborhood family are defined by means of LF-r closed set in LF topological spaces.
在LF拓扑空间中借助LF-r闭集定义了r远域族与r-远域族,进一步引入r-Lindelff可数性和弱r-Lindelff可数性的概念,证明了r-Lindel可数性和弱r-Lindel可数性对于LF-r闭子集是遗传的,是r拓扑性质。

In this paper we introduce L-smooth semi -open and L-smooth semi-closed sets in an L-smooth topological space in view of the definition of A.
Sostak给出的L-smooth拓扑空间中,定义r-内部与r-闭包,r-半开集与r-半闭集,研究了它们的一些基本性质。
6) LF-r open set
LF-r开集
1.
The relationships between general topological space and its induced space, weak induced space and its base space are discussed; r-connectivity is defined by use of LF-r open set.
