摘要
本文讨论了一种弱于开集的集合--预开集,并引入了仿强紧空间的概念,讨论了仿强紧空间的性质,最后用预开集的语言刻划了:H-闭及仿 H-闭空间.
In this paper,we discuss the weaker open sets-pre-open sets.We still intrduce para-strongly com-
pact spaces and discuss his several propertices.Lastly,we describe H-closed sPaces and para-H-closed
spaces in terms of pre-open sets.
