S-可数性

S-Countability

在拓扑空间中利用S-基和局部S-基,提出第一S-可数性公理和第二S-可数性公理,同时对S-基与局部S-基,第一S-可数性与第二S-可数性之间的关系进行探讨,得出一些新结果.

Abstract： The first S-countability axiom and the second S-countability axiom are put forward based on S-base and local S-base in topological space, meanwhile, the relationship among S-base, local S-base, the first S-countability and the second S-countability is discussed, as a result, some new results are obtained.
