$\delta$-$r$-Hyperideals and $\phi$-$\delta$-$r$-Hyperideals of Commutative Krasner Hyperrings

open access: yes, 2021
In this paper, our purpose is to define the expansion of $r$-hyperideals and extend this concept to $\phi$-$\delta$-$r$-hyperideal. Let $\Re$ be a commutative Krasner hyperring with nonzero identity. Given an expansion $\delta$ of hyperideals, a proper hyperideal $N$ of $\Re$ is called $\delta $-$r$-hyperideal if $a\cdot b\in N$ with $ann(a)=0$ implies

Merging N-hyperideals and J-hyperideals in one frame

open access: yes
The notions of N-hyperideals and J-hyperideals as two classes of hyperideals were recently defined in the context of Krasner (m,n)-hyperrings. These concepts are created on the basis of the intersection of all n-ary prime hyperideals and the intersection of all maximal hyperideals, respectively. Despite being vastly different in many aspects, they shar

Sur la rigidité de polyèdres hyperboliques en dimension $3$ : cas de volume fini, cas hyperidéal, cas fuchsien

open access: yes, 2004
30 pagesA hyperbolic semi-ideal polyedron is a polyedron whose vertices lie inside the hyperbolic space $\mathbf{H}^{3}$ or at infinity. A hyperideal polyedron is, in the projective model, the intersection of $\mathbf{H}^{3}$ with a projective polyhedron

m-Polar Fuzzy Hyperideals in LA-Semihypergroups

open access: yesInternational Journal of Analysis and Applications, 2019
In this paper, we initiate a study of m-polar fuzzy sets in hyperstructure theory, particularly in left almost semihypergroups. We define an m-polar fuzzy left (right, two sided) hyperideal in a left almost semihypergroup and provided some results on ...

On quasi-ternary hyperideals and bi-ternary hyperideals in ternary hypersemirings

open access: yesBoletim da Sociedade Paranaense de Matemática
In this article we introduce the notion of quasi-ternary hyperideal in ternary hypersemirings which is the generalization of one-sided hyperideal and study some properties of it. Also, we obtain some characterizations of quasi-ternary hyperideals in a ternary hypersemiring.

On Left Almost Semihyperrings

open access: yesInternational Journal of Analysis and Applications, 2018
The purpose of this article is to introduce the notion of left almost semihyperrings which is a generalization of left almost semirings. We investigate the basic properties of left almost semihyperrings.

Fuzziness and Roughness in Hyperquantales

open access: yesInternational Journal of Analysis and Applications, 2020
Theories of fuzzy set and rough set are powerful mathematical tools for modelling various types of uncertainty. In this paper, we introduce the notions of bi-hyperideal, fuzzy bi-hyperideals of hyperquantales and their related properties is given ...
