The commutative quotient structure of m-idempotent hyperrings

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
The α* -relation is a fundamental relation on hyperrings, being the smallest strongly regular relation on hyperrings such that the quotient structure R/α* is a commutative ring.

sπ-Weakly Regular Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2007
The purpose of this paper is to study a new class of rings R in which, for each a ΠR, aΠ aR aR, for some positive integer n. Such rings are called sp-weakly regular rings and give some of their basic properties as well as the relation between sp-weakly

Solvable groups derived from fuzzy hypergroups

open access: yesRatio Mathematica, 2015
In this paper we introduce the smallest equivalence relation ξ ∗ on a finite fuzzy hypergroup S such that the quotient group S/ξ ∗ , the set of all equivalence classes, is a solvable group.

Maximal Generalization of Pure Ideals [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2008
The purpose of this paper is to study the class of the rings for which every maximal right ideal is left GP-ideal. Such rings are called MGP-rings and give some of their basic properties as well as the relation between MGP-rings, strongly regular ring ...

Lymphangiectasia Mimicking Lichenoid Contact Reaction [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2023
Lymphangiectasia, otherwise known as acquired lymphangioma, is unusual to occur in the oral cavity. Among the frequently recognised forms of congenital and acquired entities, the acquired form of the lymphangiectasia may be caused due to trauma or ...

Ovoids of generalized quadrangles of order and Delsarte cocliques in related strongly regular graphs [PDF]

open access: yesJournal of Combinatorial Designs, 2017
AbstractWe investigate strongly regular graphs for which Hoffman's ratio bound and Cvetcović's inertia bound are equal. This means that, wherevis the number of vertices,kis the regularity,is the smallest eigenvalue, andis the multiplicity of. We show that Delsarte cocliques do not exist for all Taylor's 2‐graphs and for point graphs of generalized ...

A Brief Survey on the two Different Approaches of Fundamental Equivalence Relations on Hyperstructures

open access: yesRatio Mathematica, 2017
Fundamental structures are the main tools in the study of hyperstructures. Fundamental equivalence relations link hyperstructure theory to the  theory of corresponding classical structures. They also introduce new hyperstructure classes.The present paper

Digraph Complexity Measures and Applications in Formal Language Theory [PDF]

open access: yes, 2011
We investigate structural complexity measures on digraphs, in particular the cycle rank. This concept is intimately related to a classical topic in formal language theory, namely the star height of regular languages.

Regular tree languages, cardinality predicates, and addition-invariant FO [PDF]

open access: yes, 2011
This paper considers the logic FOcard, i.e., first-order logic with cardinality predicates that can specify the size of a structure modulo some number.

On the nature and origin of consumer vulnerability [PDF]

open access: yesAnali Pravnog Fakulteta u Beogradu, 2020
A consumer that is on a regular basis reasonably well-informed, and reasonably observant and circumspect may be affected by vulnerability in a particular situation. The author strongly believes that in the area of consumer protection, the abstract notion
