摘要
文章在超空间上引入了弱δ-连续集值映射等概念,以拓扑空间上的正则开(闭)集,θ-开(闭)集和δ-开(闭)集为基础得到了这种集值映射的几个等价关系,并给出了子集网的应用.
The concepts of weaklyδ-continuous set-valued mappings on super-spaces are introduced. On the basis of regular open （closed）sets,θ-open （closed）sets and δ-open （closed）setsin general topological spaces, some equivalent relations of this kind of set-valued mappings are obtained and some applications of subset-nets are given.
