1) 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。
2) LF-open(closed) set
LF-r开(闭)集
3) 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.
利用LF-r开集定义了r连通性,得出了弱诱导的LF拓扑空间是r连通的当且仅当其底空间是r连通的,并且分析(弱)诱导空间的结构。
4) L-Fuzzy-r semiopen set
LF-r半开集
5) generalized L fuzzy closed set
广义LF闭集
6) L-weak-r semiopen set
LF-弱r半开集
