Cyclic semi-hypergroups and hypergroups

open access: yes, 1981
It is natural to expect that, as it happens for the cyclic subgroups in the theory of groups, the cyclic subhypergroups and subsemihypergroups play an important role in the theory of hypergroups and semihypergroups. This work deals with the study of this subject.

THE TRANSPOSITION AXIOM IN HYPERCOMPOSITIONAL STRUCTURES

open access: yesRatio Mathematica, 2011
The hypergroup (as defined by F. Marty), being a very general algebraic structure, was subsequently quickly enriched with additional axioms. One of these is the transposition axiom, the utilization of which led to the creation of join spaces (join ...

Chemical Examples in Hypergroups

open access: yesRatio Mathematica, 2003
Hypergroups first were introduced by Marty in 1934. Up to now many researchers have been working on this field of modern algebra and developed it. It is purpose of this paper to provide examples of hypergroups associated with chemistry.

Generalized Fuzzy Rough Approximations on Hypergroups

open access: yesMathematics
In this paper, we define the fuzzy set-valued homomorphisms of the canonical hypergroups as a generalization of fuzzy congruences and investigate some of their features.

HX-groups and Hypergroups

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
One considers the hypergroups associated with the HX-groups Z=nZ and with the set of square matrices of order 2, with coefficients in Z=2Z and one calculates their fuzzy grade.

Multidimensional negative definite functions on the product of commutative hypergroups

open access: yesKuwait Journal of Science, 2016
The main aim of this paper is to give the integral representations for the so called multidimensional negative definite functions defined on the product of commutative hypergroups.
