半同胚空间类的半基与半可数性公理

Semi-base of Semi-topological classes and Semi-countable axiom

本文引入了半同胚空间类和半开结构的半可数性公理等概念,并结出了它们之间的一些关系。最后,利用半基的概念还给出了半紧致性的一个等价形式。

In this paper, We introduce some concept of countable axiom of Semitopological classes and Semiopen structure, and study them relatien. Finally.We give a identical form of semi-compact to use concept of semi-base.
