On the γ n -complete hypergroups and K H hypergroups
Acta Mathematica Sinica, English Series, 2008The notion of the \(\gamma_n\)-complete hypergroups is introduced and studied. This notion is similar to the \(n\)-complete hypergroups. Several results and examples on the topic are presented. The main result is: If a hypergroup is \(\gamma_n\)-complete then \(\gamma^*=\gamma_n\). The paper also presents results on the \(K_H\)-hypergroups.

Some results for strongly fuzzy grade of special complete hypergroups
2015 4th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS), 2015The study of hyperstructures connected with fuzzy sets represents a growing and new line of research spanning over the last twenty years. The starting point of this contribution is the connection between hypergroupoids and fuzzy sets established by Corsini he has associated a join space with a fuzzy set and then a fuzzy set with a hypergroupoid ...

Atanassov's intuitionistic fuzzy grade of a class of non-complete 1-hypergroups
Journal of Intelligent & Fuzzy Systems, 2014This paper continues the study of the length of the sequence of join spaces and Atanassov's intuitionistic fuzzy sets associated with a hypergroup H. The classes of non-complete 1-hypergroups are considered and analyzed their Atanassov's intuitionistic fuzzy grade.

Fuzzy roughness of n-ary hypergroups based on a complete residuated lattice
Neural Computing and Applications, 2010This paper considers the relationships among L-fuzzy sets, rough sets and n-ary hypergroup theory. Based on a complete residuated lattice, the concept of (invertible) L-fuzzy n-ary subhypergroups of a commutative n-ary hypergroup is introduced and some related properties are presented.

FUZZY GRADE OF THE COMPLETE HYPERGROUPS
2012This paper continues the study of the connection between hyper- groups and fuzzy sets, investigating the length of the sequence of join spaces associated with a hypergroup. The classes of complete hypergroups and of 1-hypergroups are considered and analyzed in this context.

Invariant $��$-means on multiplier completion of Banach algebras with application to hypergroups
2019Let ${\mathcal A}$ be a Banach algebra and let $ $ be a non-zero character on ${\mathcal A}$. Suppose that ${\mathcal A}_M$ is the closure of the faithful Banach algebra ${\mathcal A}$ in the multiplier norm. In this paper, topologically left invariant $ $-means on ${\mathcal A}_M^*$ are defined and studied.

Completely simple and regular semi hypergroups.
2012The concept of `simple' hypergroups is introduced and results on them are obtained. Constructions on these hyperstructures are defined and studied. The main results are on the product structures.

In this paper the authors carry on the analysis of cyclic, complete hypergroups, which they had begun in a precedent pater [13]. They investigate especially the "cyclity" and characterize better its role in the theory. They obtain several results which, in particular those regarding the classes of isomorphisms, the combinatorial look comes out.
