On the γ n -complete hypergroups and K H hypergroups

Acta Mathematica Sinica, English Series, 2008
The 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.

Fuzzy roughness of n-ary hypergroups based on a complete residuated lattice

Neural Computing and Applications, 2010
This 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.

Atanassov's intuitionistic fuzzy grade of a class of non-complete 1-hypergroups

Journal of Intelligent and Fuzzy Systems, 2014
This 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.

Completely semiprime hyperideals in ternary semi hypergroups

AIP Conference Proceedings, 2021
In this article we study some properties of principal hyperideal; completely semiprime hyperideal of a ternary semi hypergroup and characterized them. The interrelation among them is examined in ternary semi hypergroups extending the related results from semigroups.

FUZZY GRADE OF THE COMPLETE HYPERGROUPS

2012
This 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.
