A structure theorem for 2-hypergroupoids with topological applications

Collectanea Mathematica, 1985
\textit{H. Brandt} gave, in 1940, a structure theorem for connected groupoids G, which in modern terms says that any vertex group G(x) of G is a strong deformation rectract of G [Vjschr. Naturforsch. Ges. Zürich 85, Beibl. No. 32, 95-104 (1940; Zbl 0023.21404)].

Feebly associativeP-hypergroupoids

Rendiconti del Circolo Matematico di Palermo, 2000
The concept of \(P\)-hyperoperation on a semihypergroup, using any subset, was introduced in the early 1980's. In this paper, it is studied the class of \(P\)-hypergroupoids when they satisfy the feebly associative property. Properties of the feebly associative \(P\)-hypergroupoids related to the \(\beta^*\) relation are obtained. It is also considered

Hypergroupoids and cryptosystems

Journal of Discrete Mathematical Sciences and Cryptography, 2002
Abstract The GW-hypergroupoids are defined as generalization of the Wall hypergroupoids. The authors introduce a system to obtain a ciphertext using a GW-hypergroupoid. Conditions are given on the GW-hypergroupoid to univocally decipher a given ciphertext and to protect the original message and the key.

On the Center of a Hypergroupoid

Bulletin of the Iranian Mathematical Society, 2019
The authors introduce the definition of the center of a hypergroupoid and study its characteristics. In addition, they introduce an isomorphism action on groupoids and provide a relation between the center of a particular hypergroupoid and the center elements.

Hypercongruences in fuzzy AG-hypergroupoids

Journal of Intelligent & Fuzzy Systems, 2020
 We introduce the notion of fuzzy Abel-Grassmann’s hypergroupoid, hypercongruence, fuzzy hypercongruence, fuzzy strong hypercongruence, compatible relations in an Abel-Grassmann’s hypergroupoid. This paper is aimed to study fuzzy hyperideals, smallest fuzzy hyperideals, fuzzy equivalence relations, fuzzy compatible fuzzy strong compatible,

Associativity Test in Hypergroupoids

36th International Symposium on Multiple-Valued Logic (ISMVL'06), 2006
To test whether a groupoid is a semigroup can be tedious and the same difficulty arises for partial hypergroupoids. We adapt Light’s associativity test to partial hypergroupoids and for finite hypergroupoids express it in matricial terms.

FUZZY PSEUDOTOPOLOGICAL HYPERGROUPOIDS

2009
On a hypergroupoid one can define a topology such that the hy- peroperation is pseudocontinuous or continuous. In this paper we extend this concepts to the fuzzy case. We give a connection between the classical and the fuzzy (pseudo)continuous hyperoperations.

An overview of topological hypergroupoids

Journal of Intelligent & Fuzzy Systems, 2018
On a hypergroup, one can define a topology such that the hyperoperation is pseudocontinuous. The purpose of this paper is to study examples of topological hypergroupoids. We show that there is no relation (in general) between pseudotopological and strongly pseudotopological hypergroupoids. In particular, we present a topological hypergroupoid that does
