摘要
利用p-开集(又称准开集)定义了Pi(i=0,1,2,3,4)空间,讨论了它们的性质及Pi(i=0,1,2,3,4)空间与Ti(i=0,1,2,3,4)空间的关系;同时给出了p-覆盖的定义,继而定义了一种新的紧致空间——P-紧致空间,讨论了它的性质及P-紧空间与Pi空间的关系,得到一些很好的性质.
Using p-open sets,the authors give the definition of Pi （i=0,1,2,3,4） spaces and discuss their characters. The author also define p-cover and discuss the relations between Pi （i=0,1,2,3,4） spaces and Ti （i=0,1,2,3,4） spaces. A new compact space P-compact space is defined,and the characters of P-compact space and the relations between P-compact space and Pi-space are discussed. Thus,several conclusions are drawn.
