On the semi‐sub‐hypergroups of a hypergroup
International Journal of Mathematics and Mathematical Sciences, Volume 14, Issue 2, Page 293-304, 1991., 1989 In this paper we study some properties of the semi‐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 Frattin′s hypergroup. We also present Helly′s Theorem as a corollary of a more general Theorem.

On an extension of the notion of Reedy category [PDF]
, 2008 We extend the classical notion of a Reedy category so as to allow non-trivial automorphisms. Our extension includes many important examples occuring in topology such as Segal's category Gamma, or the total category of a crossed simplicial group such as ...

Augmented, free and tensor generalized digroups
Open Mathematics, 2019 The concept of generalized digroup was proposed by Salazar-Díaz, Velásquez and Wills-Toro in their paper “Generalized digroups” as a non trivial extension of groups.

Application of (m, n)-Г-Hyperideals in Characterization of LA-Г-Semihypergroups
Discussiones Mathematicae - General Algebra and Applications, 2019 In this paper, we study the concept of ordered (m, n)-Г-hyperideals in an ordered LA-Г-semihypergroup. We show that if (S, Г, ◦,⩽) is a unitary ordered LA-Г-semihypergroup with zero 0 and satisfies the hypothesis that it contains no non-zero nilpotent (m,

(∈γ, ∈γ ∨qδ)-fuzzy right ideals of Intra-Regular Abel Grassmann’s-Groupoids
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 In this paper, we introduce (∈γ, ∈γ ∨qδ)-fuzzy right ideals in an AG-groupoid. We characterize intra-regular AG-groupoids using the properties of (∈γ, ∈γ ∨qδ)-fuzzy subsets and (∈γ, ∈γ ∨qδ)-fuzzy right ideals.

Finite AG-groupoid with left identity and left zero [PDF]
, 2001 A groupoid G whose elements satisfy the left invertive law: (ab)c=(cb)a is known as Abel-Grassman's groupoid (AG-groupoid). It is a nonassociative algebraic structure midway between a groupoid and a commutative semigroup.
