摘　　要：该文讨论了连续映射、强不定映射的互不蕴含关系,研究了强不定映射、强半连续映射下拓扑空间的连通性、紧致性,并定义了弱S—闭空间,讨论它与S—闭空间之间的关系。This article discusses the mutual non-implication correlation between continuous mapping and strong indefinite mapping,studies the connectivity and compactness of topological spaces under strong indefinite mapping and strong semi-continuous mapping,defines the weakly S-closed space,and discusses its relationship with the S-closed space.

关 键 词：连续映射 强不定映射 弱S—闭空间 S—闭空间 连通空间
