Relative star normal type
چکیده انگلیسی
In their study of relative metric spaces, Arkhangel'skiÄ­ and Gordienko introduce several relative properties of paracompactness type. We investigate the relationships between these properties and other relative properties of paracompactness type and answer two questions raised by Arkhangel'skiÄ­ and Gordienko. TheoremIf Y is strongly regular in X and 3 paracompact in X then Y is star normal in X.TheoremY is strongly star normal in X if and only if Y is Aull paracompact in X.CorollaryIf Y is strongly star normal in X then Y is 2-paracompact in X.CorollaryIf Y is properly metrizable in X then Y is strongly star normal in X.
