摘要
在一般拓扑空间中引入了广义不定映射、广义准半开映射、广义准半闭映射和广义半同胚映射的概念,给出了这些映射的基本性质及它们之间的关系,并建立了广义半同胚定理.
The concepts of generalized irresolute mapping, generalized pre-semi-open mapping, generalized pre-semi-closed mapping and generalized semi-homeomorphism mapping are introduced in general topological spaces. The basic properties of them and relations between them are given. The semi-ho- meomorphism theorem is established.
