Reconstruction inversion formulas for the Laguerre Gabor transform

Journal 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.

Fundamental Functor Based on Hypergroups and Groups [PDF]

Mathematics Interdisciplinary Research, 2018
The purpose of this paper is to compute of fundamental relations of hypergroups. In this regards first we study some basic properties of fundamental relation of hypergroups, then we show that any given group is isomorphic to the fundamental group of a ...

Hypergroups and Geometric Spaces

Ratio 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.

Fuzzy Multi-Hypergroups

Mathematics, 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 ...

$L^p$-Conjecture on Hypergroups [PDF]

Sahand Communications in Mathematical Analysis, 2018
In this paper, we study $L^p$-conjecture on locally compact hypergroups and by some technical proofs we give some sufficient and necessary conditions  for a weighted Lebesgue space  $L^p(K,w)$ to be a convolution Banach algebra, where ...

Sul concetto di lateralizzazione nelle iperstrutture.

Ratio 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

Journal 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 ...
