Add to ORKGOne characterizes the structure of cyclic hypergroups, in particular of the complete ones. One extends to the hypergroups, some notions of group theory, as torsion, generators etc. and finds results which concern them
In this paper the notion of simple and completely simple semi hypergroups are introduced. Basic prop...
