1.
In this paper, we investigate the paracompact property and ■-characteristic, and using the concept of k-net and Paul O’Meara’s results, obtain the descriptions of paracompact property and ■-characteristic of point-compact continuous multifunction space with compact-open topology.
本文研究了集值映射空间类上的仿紧性和■特征,利用k网的概念及Paul O’Meara等人的结论,得到了点紧致连续集值映射族依紧开拓扑下的仿紧性和特征的刻画。
2.
In this paper, the relations among the point-compact continuous multifunction spaces under compact-open topology, uniform convergence topology, uniform convergence topology on compacta and metric topology, from a topology space to a metric space, are investigated.
本文研究拓扑空间到一致空间上点紧致的连续集值映射空间在紧开拓扑、一致收敛拓扑、紧致处一致收敛拓扑和度量拓扑等之下它们之间的关系,利用诱导映射和嵌入的方法给出了拓扑空间到实直线上点紧致的连续集值映射空间可度量化的若干等价条件。
3.
In this paper,we discuss some properties of the point-compact continuous multifunction spaces with compact-open topology and show that if X,Y are N_0-space,then the point-compact con- tinuous multifunction space with compact-open topology is an N_0-space,which is a generalization of a corresponding result concerning continuous single-valued function spaces proved by E.
本文讨论了点紧致的连续集值映射空间在赋予紧开拓扑下的某些拓扑性质,证明了:若X,Y为N_0空间,则X到Y上的点紧致的连续集值映射族依紧开拓扑是N_0空间,从而将Michael的结论推广到更大的映射空间类上。

The separabilities of the point-closed continuous multifunction spaces with Γ-open topology are discussed and the internal relations between the separabilities of the point-closed continuous multifunction spaces and the separabilities of image spaces are obtained.
