A co-topological application to minimal spaces

Giovanni Viglino

Vol. 27 (1968), No. 1, 197–200
Abstract

A space (X,τ) which satisfies a topological property P is said to be minimal-P if T = {ττ is a P-topology on X;ττ} = . For example, a Hausdorff space (X,τ) is minimal Hausdorff if there exists no Hausdorff topology on X which is strictly weaker than τ. The purpose of this paper is to show that for certain properties one need only consider a subset of T “induced” by τ to determine if (X,τ) is minimal-P.
