C-hypergroupoids obtained by special binary relations

Computers and Mathematics With Applications, 2010
In this paper we deal with the partial or non-partial C-hypergroupoids which are associated with special binary relations defined on H, such as Reflexive, Symmetric, Cyclic and Transitive.

Binary relations and hypergroupoids

, 2000
The author associates a partial hyperoperation \(\langle\widetilde\circ_R\rangle\) to every binary relation \(R\) defined on a non-empty set \(H\) in the following way: \(x\widetilde\circ_R y=\{z\in H\mid xRz,\;zRy\}\). The hyperstructure \(\langle H,\widetilde\circ_R\rangle\) is a partial hypergroupoid and the necessary and sufficient condition so ...

Soft hyperstructure

Computers and Mathematics With Applications, 2011
In this paper, we study soft hypergroupoids. Firstly, we introduce the notion of soft hypergroupoids, and some examples are given. Also, we show that soft hypergroupoids are closely related to L-subhypergroupoid.

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 ...

Results on generalized intuitionistic fuzzy hypergroupoids

Journal of Intelligent & Fuzzy Systems, 2019
 In this paper, we introduce and study the concept of generalized intuitionistic fuzzy hypergraph (shortly, g-if-hypergraph) and establish a relation between generalized if-hypergraph and if-hyperstructures. Further, we introduce partial if-hypergroupoid and extend the results for higher order if-hypergroupoids and study their properties.

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.
