Finitely generated hypergroups

open access: yes, 1986
The authors define finitely generated hypergroups and prove (among other things) the following result: A hypergroup H and every subhypergroup complete part of it are finitely generated if and only if H satisfies the ACC for complete parts.

Applicazioni (h,A)-lineari omomorfismi di M_A-ipergruppoidi

open access: yes, 2001
In the papers [9], [10] we introduced and studied M_λ -hypergroupoids; also, we obtained some results on the automorphism group of a G_ λ -hypergroupoid.

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.

On the borderline of fields and hyperfields, part II -- Enumeration and classification of the hyperfields of order 7

open access: yes
The quotient hyperfield is a landmark on the borderline of fields and hyperfields. In this paper, which is the second part of our previously published paper, all the hyperfields of order 7 are constructed, enumerated and presented, in the course of which

Fourier Analysis of Local Fell Groups

open access: yes
In 1972, Bagget showed that a separable locally compact group G is compact if and only if its dual space G^ is discrete. Curiously however, there are non-discrete groups whose duals are compact, and such a group was identified in the same paper.

Completely semiprime hyperideals in ternary semi hypergroups

AIP Conference Proceedings, 2021
In this article we study some properties of principal hyperideal; completely semiprime hyperideal of a ternary semi hypergroup and characterized them. The interrelation among them is examined in ternary semi hypergroups extending the related results from semigroups.

On the γ n -complete hypergroups and K H hypergroups

Acta Mathematica Sinica, English Series, 2008
The notion of the \(\gamma_n\)-complete hypergroups is introduced and studied. This notion is similar to the \(n\)-complete hypergroups. Several results and examples on the topic are presented. The main result is: If a hypergroup is \(\gamma_n\)-complete then \(\gamma^*=\gamma_n\). The paper also presents results on the \(K_H\)-hypergroups.
