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.

A note on quasi-Steiner hypergroupoids

Journal of Discrete Mathematical Sciences and Cryptography, 2003
Abstract The class of hyperstructures called quasi-Steiner hypergroupoids are studied and their group of automorphisms are found in some interesting cases. In particular, there exist quasi-Steiner hypergroupoids (H, ○) which group of automorphisms is exactly the group of automorphisms fixing a point and a line in the geometric space associated to (H, ○)

Matroidal \(M_\lambda\)-hypergroupoids. \(\lambda\)-linear mappings and automorphisms of \(M_\lambda\)-hypergroupoids

, 1998
In this paper a thoroughgoing study of hypergroupoids considered by the author in a previous work [Matematiche 52, No. 2, 271-295 (1997; Zbl 0941.20071)] is done. Let \(G\) be a group, \(\lambda\in G\) and \(\cdot\colon G\times M\) be an action of \(G\) on \(M\). The aim of this paper is to investigate the hyperoperation defined on \(M\) by: \(a\cdot b=

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.

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.

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

Program to determine the fuzzy grade of a hypergroupoid

Journal of Algebraic Hyperstructures and Logical Algebras
In this paper, we present a program to determine the fuzzy grade of a hypergroup and we exemplify for a certain class of hypergroups associated with genetics.

Hypergroups associated with hypergraphs

Discret. Math. Algorithms Appl., 2020
The purpose of this paper is the study of hypergroups associated with hypergraphs. In this regard, we construct a hypergroupoid by defining a hyperoperation on the set of degrees of vertices of a hypergraph.
