More on sg-compact spaces. (English) Zbl 0989.54026
Summary: The aim of this paper is to continue the study of sg-compact spaces, a topological notion much stronger than hereditary compactness. We investigate the relations between sg-compact and \(C_2\)-spaces and the interrelations to hereditarily sg-closed sets.
