Abstract

It is the purpose of this paper to characterize countably subparacompact spaces in a number of ways and to point out similarities in the pathologies of countably subparacompact spaces and normal spaces. It will be shown inter alia, that a space is countably subparacompact if and only if it is countably a-paracompact, and also if and only if it is countably metacompact and subnormal. The well known product of ordinal spaces, W × W^∗, is shown to be not countably subparacompact, despite the fact that W^∗ is compact and W is countably subparacompact and normal.
