Theorem Suppose Y is strongly regular in the space X. If Y is paracompact in X then Y is collectionwise normal in X. Example A T2 space X having a subspace which is 1− paracompact in X but not collectionwise normal in X. Theorem Suppose that Y is s- regular in the space X. If Y is metacompact in X and strongly collectionwise normal in X then Y is paracompact in X.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)ParacompactCollectionwise normaRelative topological propertiesArtículo2017-06-0810.4995/agt.2004.1970Abierto1989-4147
