On Some Homological Properties of Hypergroup Algebras with Relation to Their Character Spaces
Journal of Mathematics, 2022 In this paper, we study the notion of approximate biprojectivity and left φ-biprojectivity of some Banach algebras, where φ is a character. Indeed, we show that approximate biprojectivity of the hypergroup algebra L1K implies that K is compact. Moreover,

The non-commuting graph of a non-central hypergroup
Open Mathematics, 2019 The aim of this paper is to construct and study the properties of a certain graph associated with a non-central hypergroup, i.e. a hypergroup having non-commutative the associated fundamental group.

ASSOCIATED (SEMI)HYPERGROUPS FROM DUPLEXES [PDF]
Journal of Algebraic Systems, 2015 In this paper using strongly duplexes we introduce a new class of (semi)hypergroups. The associated (semi)hypergroup from a strongly duplex is called duplex (semi)hypergroup.

A (Discrete) Homotopy Theory for Geometric Spaces
Journal of Mathematics, Volume 2023, Issue 1, 2023., 2023 We define the concepts of homotopy and fundamental group for geometric spaces as a generalization of metric spaces, digital spaces, and graphs; then, we compare them with corresponding concepts in these spaces. Also, we state some properties of the fundamental group of geometric spaces and some theorems to calculate them.
