摘要
本文讨论了非空集上保并增值映射的性质及其与复盖之间的关系,给出一族保并增值映射可以诱导出一个拓扑的条件,定义了保并增值映射正规列,并以此描述了完全正规空间、M—空间念。
In this paper, we study the relations between the covering and the union-preserving value-increasing maPping of X, and give the descriptions of the fully normal space and M-space by means of unionpreserving value-increasing mappings.
