集值映射空间在紧开拓扑下的N性质
ON N-PROPERTY OF MULTIFUNCTION SPACES WITH COMPACT-OPEN TOPOLOGY
摘要
Abstract
This paper discusses the (N) property of point-compact continuous multifunction spaces with compact-open topology.By using a cs-σ-network,it obtains that if X is an (N)0-space,Y is an (N)-space,then the point-compact continuous multifunction space with compact-open topology is an (N)-space.This generalizes J.A.Guthrie's results to wider topological space,and improves relevant conclusions.关键词
