The paper deals with fuzzy sets and hyperstructures. It is a new growing field and the paper focuses on \(f\)-hypergroups. In a set equipped with an \(f\)-hyperoperation the associativity and the reproductivity are studied. The relations of the defined classes of fuzzy hypergroups are presented and equivalent conditions, on hypergroups defined on the ...

On the fuzzy grade of hypergroups
Fuzzy Sets and Systems, 2008The paper deals with the connection of fuzzy sets and of join spaces with a hypergroupoid. For the last connection, introduced by Corsini in 2003, the second author obtained some results in 2007. In this paper the authors continue to obtain results in this direction.

Starting from a given hypergroupoid \((H,\circ)\) and using the notion of the complete closure (of the non-empty hyperproduct of two arbitrary elements of \((H,\circ)\)), a new hyperproduct is defined on \(H\) and the concept of the complementary hypergroupoid is introduced. The authors study the properties of the previous complementary hyperstructures,

Generalization ofP-hypergroups
Rendiconti del Circolo Matematico di Palermo, 1987A hypergroup, in the sense of Marty (1934), is a set H equipped with an associative hyperoperation \(\cdot: H\times H\to P(H)\) which satisfies the property that \(xH=Hx=H\), for all \(x\in H\). We consider hypergroups constructed from ordinary semigroups which generalizes the notion of P- hypergroups introduced by the author [Acta Univ.

Results on i.p.s. hypergroups.
J. Multiple Valued Log. Soft Comput., 2003Summary: We first construct an i.p.s. hypergroup from an arbitrary finite i.p.s. hypergroup. Then we show that for each positive integer \(n\), there is an i.p.s. hypergroup (which is not a group) of order \(n\). Finally we give some classifications of i.p.s. hypergroups of order 9.
