本文主要研究了具有性质P的相对可数紧空间的相对紧性质,其中性质P分别代表相对Lindel~f性质,相对仿紧性,相对亚紧性和相对次仿紧性质,举例说明了所给出的条件是不可减弱的.
In this paper, we mainly study relative compactness of relatively countable compactness space with some property P, where property P represents relative Lindel~f property, relative paracompactness, relative metacompactness and relative subparacompactness, we also provide some examples to explain what we give conditions can not be weaken.
