1) remote-neighborhood mappings
远域映射族
1.
metric on a completely distributive lattice are given by using pure distance function and remote-neighborhood mappings,and its applications become more convenient.
度量的纯距离函数式刻划与远域映射族式刻划,从而使其更直观且便于应用。

3) r remote neighborhood family
r远域族
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。
