Convolution semigroups on hypergroups [PDF]

Pacific Journal of Mathematics, 1987
For convolution semigroups \(\mu =(\mu_ t)_{t>0}\) on abelian hypergroups K a representation theorem is derived which extends earlier results of this (``Levy-Hinčin'') type: Roughly speaking a [abelian] hypergroup is a locally compact K with involution \({\;}^-\) on K and abstract convolution * on the bounded complex Borel measures on K which is ...

Algorithms for determining the type of algebraic hyperstructures and morphisms [PDF]

Mathematics and Computational Sciences
In this paper, we present some primary methods to define a hypergroupoid by algorithm. Then, we present algorithms for checking if it is closed under ο, associativity, weak associativity, commutativity, weak commutativity, establishing the reproduction ...

Cyclic semi-hypergroups and hypergroups

, 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.

On Certain Proximities and Preorderings on the Transposition Hypergroups of Linear First-Order Partial Differential Operators

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
The contribution aims to create hypergroups of linear first-order partial differential operators with proximities, one of which creates a tolerance semigroup on the power set of the mentioned differential operators.

?-Independent and Dissociate Sets on Compact Commutative Strong Hypergroups [PDF]

Journal of Sciences, Islamic Republic of Iran, 2008
In this paper we define ?-independent (a weak-version of independence), Kronecker and dissociate sets on hypergroups and study their properties and relationships among them and some other thin sets such as independent and Sidon sets.

Chemical hyperstructures for Astatine, Tellurium and for Bismuth

Bulletin of Computational Applied Mathematics, 2019
The concept of weak algebraic hyperstructures constitutes a generalization of the well-known algebraic hyperstructures. The aim of this paper is to present some of the results, methods and ideas about chemical examples of weak algebraic hyperstructures.

Fuzzy Aspects Associated with Biological Inheritance

Mathematics
Genetics explores the mechanisms of heredity and trait variation across organisms, with foundational principles established by Gregor Mendel through experiments on monohybrid and dihybrid crosses. The mathematical framework of hypergroups can effectively
