关于不定映射与半粘合映射的几个图形交换定理

Several Commutation Theorems of Graph about Irresolute Mapping and Semi-Identification Mapping

本文在文献[1]和[2]的基础上进一步研究了不定映射与半粘合映射,给出了关于它们的几个图形交换定理,所得到的结果完善了文献[1]和[2]的研究。

In this paper we further studied the irresolute mapping and semi - identification mapping on the base of references [l]and [2] ,and obtained several commutation theorems of graph. these resalts perfected the study of references [1]and [2].
