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

open access: yesMathematical 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.

Contribution to study special kinds of hyperideals in ordered semihyperrings

open access: yesJournal of Taibah University for Science, 2017
In the present paper, we introduce the notion of k-hyperideals on ordered semihyperrings. Then, we investigate some fundamental properties of k-hyperideals of ordered semihyperrings.

Regularity in terms of Hyperideals [PDF]

open access: yesChinese Journal of Mathematics, 2013
This paper deals with the algebraic hypersystems. The notion of regularity of different type of algebraic systems has been introduced and characterized by different authors such as Iseki, Kovacs, and Lajos. We generalize this notion to algebraic hypersystems giving a unified generalization of the characterizations of Kovacs, Iseki, and Lajos.

Hyperideal polyhedra in hyperbolic 3-space [PDF]

open access: yesBulletin de la Société mathématique de France, 2002
The authors consider here hyperideal polyhedra. Thought of as projective polyhedra, these are intersections of the hyperbolic space \(\mathbb{H}^3\) with polyhedra, all of whose vertices lie outside \(\mathbb{H}^3\) (they may lie on the absolute). In this paper, such polyhedra are completely classified up to isometry in terms of their combinatorial ...

Hyperideals of (Finite) General Hyperrings

open access: yesMathematics Interdisciplinary Research, 2021
A general hyperring is an algebraic hypercompositional system (R,+,·) with two hyperoperations ”+" and ” · ”, such that for all x,y ∈ R, x + y and x · y are non-empty subsets of R, and R satisfies the axioms similar to a ring. We introduce and study hyperideals of a general hyperring.

Classes of $F$-hyperideals In A Krasner $F^{(m,n)}$-Hyperring [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
‎Krasner $F^{(m,n)}$-hyperrings were introduced and  investigated by Farshi and Davvaz. In this paper, our purpose is to  define and characterize  three particular classes of $F$-hyperideals in a Krasner $F^{(m,n)}$-hyperring, namely prime $F ...

On Minimal and Maximal Hyperidealsin n-ary Semihypergroups

open access: yesMathematics, 2020
The concept of j-hyperideals, for all positive integers 1≤j≤n and n≥2, in n-ary semihypergroups, is a generalization of the concept of left, lateral and right hyperideals in ternary semihypergroups.

On volumes of hyperideal tetrahedra with constrained edge lengths

open access: yes, 2019
Hyperideal tetrahedra are the fundamental building blocks of hyperbolic 3-manifolds with geodesic boundary. The study of their geometric properties (in particular, of their volume) has applications also in other areas of low-dimensional topology, like ...

Primal hyperideals of multiplicative hyperring

open access: yes, 2021
Summary: In this paper, we introduce the concepts of adjoint, \(\mathrm{n}\)-adjoint of a hyperideals and primal and \(\mathrm{n}\)-primly hyperideals of a commutative multiplicative hyperrings. Many results con-cerning prime, \(\mathrm{n}\)-primly, primary and primal hyperideals of a commutative multiplicative hy-perrings are given, illustrated by ...
