Some properties of certain Subhypergroups

Christos G. Massouros


The structure of the hypergroup is much more complicated than that of the group. Thus there exist various kinds of subhypergroups.
This paper deals with some of these subhypergroups and presents certain properties of the closed, invertible and ultra-closed subhypergroups.
