1) R-subset
R-子集
2) r-order subset
r-阶子集
3) relative R-subset
相对R-子集
1.
The concepts of R-KKM map and relative R-subset on general topological spaces were introduced and,by using the classical KKM principle,the open [closed] version of KKM type theorem on general topological spaces was obtained with a remark.
首先在一般拓扑空间上引入R-KKM映射和相对R-子集的概念,然后利用古典的KKM原理在一般拓扑空间上建立KKM型定理的开[闭]形式并给出一个注记,并根据所得结果在一般拓扑空间上得出若干个相交定理。
4) 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。
