On complementable semihypergroups
Morteza Jafarpour, Irina Cristea, Hossien Aghabozorgi, 2016, original scientific article

Abstract: n this paper, we first introduce the notion of complementable semihypergroup, proving that the classes of simplifiable semigroups, groups, and complete hypergroups are examples of complementable semihypergroups. Then we define when two semihypergroups are disjoint and find examples of such semihypergroups. Finally, we discuss on the complementable property of $K_H$-hypergroups.

A method to compute the number of regular reversible Rosenberg hypergroup
Ali Tavakoli, Morteza Jafarpour, Irina Cristea, 2016, original scientific article

Abstract: The purpose of this note is the study of the hypergroups associated with binary relations. New types of matrices, called i-very good and regular reversible matrices, are introduced in order to give some properties of the Rosenberg hypergroups related to them. A program written in $MATLAB$ computes the number of these hypergroups up to isomorphism.
