Algebraic quantum hypergroups

, 2011
An algebraic quantum group is a regular multiplier Hopf algebra with integrals. In this paper we will develop a theory of algebraic quantum hypergroups. It is very similar to the theory of algebraic quantum groups, except that the comultiplication is no ...

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.

Hypergroups and their pullback and pushout structures [PDF]

, 2018
Hypergroups in the sense of Marty are very important and a rather di?cult subject to be understood since they do not generally have any identity or inverse element. Crossed modules are one of the most important tools to be applied on groups.

THE TRANSPOSITION AXIOM IN HYPERCOMPOSITIONAL STRUCTURES

Ratio 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 ...

Wiener's theorem on hypergroups [PDF]

, 2015
The following theorem on the circle group T is due to Norbert Wiener: If f∈L1(T) has non-negative Fourier coefficients and is square integrable on a neighbourhood of the identity, then f∈L2(T). This result has been extended to even exponents including p=∞

Generalized Fuzzy Rough Approximations on Hypergroups

Mathematics
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

Analele 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.

Hypergroups of compact type

, 2005
We consider commutative hypergroups with translation operators which are compact on L2 resp. L1. It will be shown that such hypergroups are necessarily discrete and that in the case of compact translations on L1 the support of the Plancherel measure ...
