Reversible hypergroups

Rendiconti del Seminario Matematico e Fisico di Milano, 1977
Usando le proprieta dei caratteri di un gruppo finito come prototipo, una nuova nozione di un ipergruppo reversibileH e introdotta che prende nota dei gradi e delle molteplicita. Molte proprieta dei gruppi finiti abeliani hanno analogie con gli ipergruppi reversibili.

Generalization ofP-hypergroups

Rendiconti del Circolo Matematico di Palermo, 1987
A 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.

Flickr hypergroups

Proceedings of the 17th ACM international conference on Multimedia, 2009
The amount of multimedia content available online constantly increases, and this leads to problems for users who search for content or similar communities. Users in Flickr often self-organize in user communities through Flickr Groups. These groups are particularly interesting as they are a natural instantiation of the content~+~relations social media ...

On fuzzy hypergroups

1997
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 ...

Intuitionistic fuzzy multi-hypergroups

2022
The authors define intuitionistic fuzzy multi-hypergroups which generalize the concept of intuitionistic fuzzy hypergroups. Some operations of these fuzzy multi-hypergroups are studied. They give some fundamental results and examples related to these conceptnotion. Besides, they study the homomorphisms and normal properties of fuzzy multi-hypergroups.

��-Amenable Hypergroups

2009
Let $K$ denote a locally compact commutative hypergroup, $L^1(K)$ the hypergroup algebra, and $ $ a real-valued hermitian character of $K$. We show that $K$ is $ $-amenable if and only if $L^1(K)$ is $ $-left amenable. We also consider the $ $-amenability of hypergroup joins and polynomial hypergroups in several variables as well as a single ...

Cyclic hypergroups and torsion in hypergroups

1980
One 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.
