Convolution operators on the dual of hypergroup algebras [PDF]

open access: yes, 2003
summary:Let $X$ be a hypergroup. In this paper, we define a locally convex topology $\beta $ on $L(X)$ such that $(L(X),\beta )^*$ with the strong topology can be identified with a Banach subspace of $L(X)^*$.

Hypergroup Graphs and Subfactors.

open access: yes, 1994
The main theme of this t hesis is hypergroups. In this thesis the the- ory of hypergroups is applied to study the relation between certain graphs and subfactors of II, factors in the context of principal graphs associated with the inclusions of II ...

Module Connes amenability of hypergroup measure algebras

open access: yes, 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 ...

Pointwise and integral estimates for the fractional integrals on the Laguerre hypergroup

open access: yes, 2012
Let K = [0,infinity) x R be the Laguerre hypergroup which is the fundamental manifold of the radial function space for the Heisenberg group. In this paper, some pointwise and integral estimates for the fractional integrals in terms of the maximal and ...

The measure algebra of a locally compact hypergroup

open access: yes, 1973
A hypergroup is a locally compact space on which the space of finite regular Borel measures has a convolution structure preserving the probability measures. This paper deals only with commutative hypergroups.

Invariant $\varphi $-means on multiplier completion of Banach algebras with application to hypergroups

open access: yes, 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.
