Abstract: 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.

Keywords: sg-compact; semi-compact; $C_2$-space; semi-open set; sg-open set; hsg-closed sets.

Classification (MSC2000): 54D30, 54A05; 54H05, 54G99
