r‐Hyperideals and Generalizations of r‐Hyperideals in Krasner Hyperrings

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
This paper deals with Krasner hyperrings as an important class of algebraic hyperstructures. We investigate some properties of r‐hyperideals in commutative Krasner hyperrings. Some properties of pr‐hyperideals are also studied. The relation between prime hyperideals and r‐hyperideals is investigated. We show that the image and the inverse image of an r‐

Applications of (Neutro/Anti)sophications to Semihypergroups

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this paper, we extend the notion of semi‐hypergroups (resp. hypergroups) to neutro‐semihypergroups (resp. neutro‐hypergroups). We investigate the property of anti‐semihypergroups (resp. anti‐hypergroups). We also give a new alternative of neutro‐hyperoperations (resp. anti‐hyperoperations), neutro‐hyperoperation‐sophications (resp.

A Study on A − I − Γ‐Hyperideals and (m, n) − Γ‐Hyperfilters in Ordered Γ‐Semihypergroups

Discrete Dynamics in Nature and Society, Volume 2021, Issue 1, 2021., 2021
The concept of almost interior Γ‐hyperideals (A − I − Γ‐hyperideals) in ordered Γ‐semihypergroups is a generalization of the concept of interior Γ‐hyperideals (I − Γ‐hyperideals). In this study, the connections between I − Γ‐hyperideals and A − I − Γ‐hyperideals in ordered Γ‐semihypergroups were presented.

On fuzzy prime and fuzzy semiprime ideals of hypergroupoids [PDF]

Journal of Hyperstructures, 2016
We deal with an hypergroupoid endowed with a rela- tion denoted by \", we call it{hypergroupoid. We prove that a nonempty subset A of a{hypergroupoid H is a prime (resp. semiprime) ideal of H if and only if the characteristic function fA is a fuzzy prime

Approximations of (∈, ∈∨qk)‐Fuzzy Hyperideals in Ordered LA‐Semihypergroups

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
This paper concerns the relationship between rough sets, (∈, ∈∨qk)‐fuzzy sets, and the LA‐semihypergroups. We proved that the lower approximation (l‐approx) and the upper approximation (u‐approx) of different hyperideals of LA‐semihypergroups become again hyperideal and also provided some examples.

[Retracted] Topological Structures of Lower and Upper Rough Subsets in a Hyperring

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this paper, we study the connection between topological spaces, hyperrings (semi‐hypergroups), and rough sets. We concentrate here on the topological parts of the lower and upper approximations of hyperideals in hyperrings and semi‐hypergroups. We provide the conditions for the boundary of hyp‐ideals of a hyp‐ring to become the hyp‐ideals of hyp ...

Hypergroupoids determined by lattices

European Journal of Combinatorics, 2010
The paper deals with hypergroupoids where the hyperoperation is determined by lattices. The main results are conditions under which the hyperoperation is associative and when a hypergroup is obtained.

Introduction to Dependence Relations and Their Links to Algebraic Hyperstructures

Mathematics, 2019
The aim of this paper is to study, from an algebraic point of view, the properties of interdependencies between sets of elements (i.e., pieces of secrets, atmospheric variables, etc.) that appear in various natural models, by using the algebraic ...

The Path Hyperoperation

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
A new class of hypergroupoids, deriving from binary relations, is presented, via the introduced path hyperoperation. Its properties are investigated and its connections with Graph Theory are also delineated.
