[Retracted] Approximations of Intuitionistic Fuzzy Ideals over Dual Spaces by Soft Binary Relations

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
The major advantage of this proposed work is to investigate roughness of intuitionistic fuzzy subsemigroups (RIFSs) by using soft relations. In this way, two sets of intuitionistic fuzzy (IF) soft subsemigroups, named lower approximation and upper approximation regarding aftersets and foresets, have been introduced.

On 1‐Absorbing Prime Hyperideal and Some of Its Generalizations

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, we introduce the concept of 1‐absorbing prime hyperideals which is an expansion of the prime hyperideals. Several properties of the hyperideals are provided. For example, it is proved that if a strong C‐hyperideal I of R is 1‐absorbing prime that is not prime, then R is a local multiplicative hyperring.

A New Approach to Evaluate Regular Semirings in terms of Bipolar Fuzzy k‐Ideals Using k‐Products

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, we provide a generalized form of ideals that is k‐ideals of semirings with the combination of a bipolar fuzzy set (BFS). The BFS is a generalization of fuzzy set (FS) that deals with uncertain problems in both positive and negative aspects. The main theme of this paper is to present the idea of (α, β)‐bipolar fuzzy k‐subsemiring (k‐BFSS),

A Generalized Decision‐Making Technique Based on Bipolar‐Valued Multivague Soft Sets

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
The decision‐making technique, launched by Roy and Maji, is considered an effective method to overcome uncertainty and fuzziness in decision‐making problems, though, adapting it to reflect the problem parameters’ vagueness, as well as multibipolarity, is very difficult. So, in this article, the bipolarity is interpolated into the multivague soft set of

An Approach to BMBJ‐Neutrosophic Hyper‐BCK‐Ideals of Hyper‐BCK‐Algebras

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this article, a new idea of BMBJ‐neutrosophic hyper‐BCK‐algebras is introduced and some of its properties are investigated. Here, BMBJ‐neutrosophic hyper‐BCK‐ideal, BMBJ‐neutrosophic weak hyper‐BCK‐ideal, BMBJ‐neutrosophic s‐weak hyper‐BCK‐ideal, and BMBJ‐neutrosophic strong hyper‐BCK‐ideal are presented, and some relevant results and relations are ...

Semilattice strongly regular relations on ordered n-ary semihypergroups

open access: yesAIMS Mathematics, 2022
In this paper, we introduce the concept of j-hyperfilters, for all positive integers 1≤j≤n and n≥2, on (ordered) n-ary semihypergroups and establish the relationships between j-hyperfilters and completely prime j-hyperideals of (ordered) n-ary ...

Polyhedral hyperbolic metrics on surfaces [PDF]

open access: yes, 2008
In the last section of \cite{CompHyp} it is proved that the map $\mathcal{I}$ is a finite-sheeted covering map between $\mathcal{P}$ and $\mathcal{M}$. As $\mathcal{M}$ is simply connected it is deduced that $\mathcal{I}$ is a homeomorphism.

On Rough Hyperideals in Hyperlattices [PDF]

open access: yesJournal of Applied Mathematics, 2013
We introduce and study rough hyperideals in hyperlattices. First, we give some interesting examples of hyperlattices and introduce hyperideals of hyperlattices. Then, applying the notion of rough sets to hyperlattices, we introduce rough hyperideals in hyperlattices, which are extended notions of hyperideals of hyperlattices.

Factorizable Ordered Hypergroupoids with Applications

open access: yesMathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
In this study, we propose the concept of factorizable ordered hypergroupoids (semihypergroups) and present several of its properties. Our goal is to construct ordered hypergroupoid from blood groups together with some other information. Finally, we discuss right magnifying elements for further research.

Non-rigidity of spherical inversive distance circle packings [PDF]

open access: yes, 2011
We give a counterexample of Bowers-Stephenson's conjecture in the spherical case: spherical inversive distance circle packings are not determined by their inversive distances.Comment: 6 pages, one ...
