, 1990 This paper is about the structure of the core of the A-hypergroups. We prove that in some A-hypergroups the core is equal to a hyperaddition of zero type and we give another example that shows the existence of some A-hypergroups for which that property ...

, 2016 Weighted group algebras have been studied extensively in Abstract Harmonic Analysis, where complete characterizations have been found for some important properties of weighted group algebras, namely, amenability and Arens regularity.

, 1991 G. Tallini in 1987 associated a unique algebra A(G) to every finite hypergroupoid G . In this paper, several necessary and sufficient conditions for the associated algebra to be associative are proved.

, 1990 . In this paper we study some properties of the seml-sub-hypergroups and the closed sub-hypergroups of the hypergroups. We introduce the correlated elements and the fundamental elements and we connect the concept antipodal of the latter with Frattln'

, 2019 Let ${\mathcal A}$ be a Banach algebra and let $\varphi $ be a non-zero character on ${\mathcal A}$. Suppose that ${\mathcal A}_M$ is the closure of the faithful Banach algebra ${\mathcal A}$ in the multiplier norm. In this paper, topologically left invariant $\varphi$-means on ${\mathcal A}_M^*$ are defined and studied.

, 1978 This paper initiates a study of Z-hypergroups, that is, commutative topological hypergroups K such that K / Z K/Z is compact where Z denotes the maximum subgroup (equivalently, the center) of K ...

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.

Dual space and hyperdimension of compact hypergroups
, 2017 We characterize dual spaces and compute hyperdimensions of irreducible representations for two classes of compact hypergroups namely conjugacy classes of compact groups and compact hypergroups constructed by joining compact and finite hypergroups.
