Dense-separable groups and its applications in -independence
Fucai Lin, Qiyun Wu, Chuan Liu
A topological space is called {\it dense-separable} if each dense subset of its is separable. Therefore, each dense-separable space is separable. We establish some basic properties…
Hyperspaces with a countable character of closed subsets
Chuan Liu, Fucai Lin
For a regular space , the hyperspace (resp., ) is the space of all nonempty closed subsets of with the Fell topology (resp., Vietoris topolo…
Some properties of Pre-topological groups
Fucai Lin, Ting Wu, Yufan Xie +1
In this paper, we pose the concepts of pre-topological groups and some generalizations of pre-topological groups. First, we systematically investigate some basic properties of pre-…
Some properties of Pre-uniform spaces
Fucai Lin, Yufan Xie, Ting Wu +1
In this paper, we introduce the notions of pre-uniform spaces and pre-proximities and investigate some basic properties about them, where the definition of pre-uniformity here is d…
