Module Connes amenability of hypergroup measure algebras

open access: yesOpen Mathematics, 2015
We define the concept of module Connes amenability for dual Banach algebras which are also Banach modules with a compatible action. We distinguish a closed subhypergroup K0 of a locally compact measured hypergroup K, and show that, under different ...

Fuzzy Multi-Hypergroups

open access: yesMathematics, 2020
A fuzzy multiset is a generalization of a fuzzy set. This paper aims to combine the innovative notion of fuzzy multisets and hypergroups. In particular, we use fuzzy multisets to introduce the concept of fuzzy multi-hypergroups as a generalization of ...

Reconstruction inversion formulas for the Laguerre Gabor transform

open access: yesJournal of Numerical Analysis and Approximation Theory
In this paper, we define and study the Gabor transform in the context of the Laguerre hypergroup. We prove some of its basic properties, such as Plancherel theorem, inversion formula and Calder´on’s reproducing inversion formula.

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 ...

Hypergroups and Geometric Spaces

open access: yesRatio Mathematica, 2012
We explain some links between hypergrpoups and geometric spaces. We show that for any given hypergroup it is possible to define a particular geometric space and then a canonical homomorphism between the hypergroup and a group.

Algorithm for Determining the Strong Fuzzy Grade of a Hypergroup

open access: yesAlgorithms
In this paper, we present an algorithm for determining the strong fuzzy grade of a hypergroup, considering a particular class of hypergroups associated with genetics. A study is carried out depending on the cardinality of the initial hypergroup. The last

Sul concetto di lateralizzazione nelle iperstrutture.

open access: yesRatio Mathematica, 1996
Given an hypcrgroup (G,?) , we introduce the concept of lower/alert)! of A (non empty subset ol' G), having geG as representative. We introduce also the notion ol‘ y-hypergroup which characterize some hyperlaterals as supports ol' subhypergroups of the y-

Littlewood-Paley -Functions and Multipliers for the Laguerre Hypergroup

open access: yesJournal of Inequalities and Applications, 2011
Let where . Then can generate a hypergroup which is called Laguerre hypergroup, and we denote this hypergroup by K. In this paper, we will consider the Littlewood-Paley -functions on K and then we use it to prove the Hölmander multipliers on ...
