摘　　要：以G-方法及G-邻域为基础,在拓扑空间中引入G-聚点、G-导集、G-序列导集和G-边缘的概念并讨论其相应的性质,推广了拓扑空间中有关导集和边缘的若干结果.Based on G-methods and G-neighborhoods,the author introduces the concepts of G-cluster points,G-derived sets,G-sequential derived sets and G-boundary in topological spaces,discusses its corresponding properties and extends some related results of derived sets and boundary in topological spaces.
