On Local Rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2014
A ring R is called local ring if it has exactly one maximal ideal. In this paper, we introduce some characterization and basic properties of this ring. Also, we studied the relation between local rings and Von Neumann regular rings and strongly regular ...

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 ...

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.

Switched graphs of some strongly regular graphs related to the symplectic graph [PDF]

open access: yesDesigns, Codes and Cryptography, 2017
Applying a method of Godsil and McKay \cite{GM} to some graphs related to the symplectic graph, a series of new infinite families of strongly regular graphs with parameters $(2^n\pm2^{(n-1)/2},2^{n-1}\pm2^{(n-1)/2},2^{n-2}\pm2^{(n-3)/2},2^{n-2}\pm2^{(n-1)/2})$ are constructed for any odd $n \geq 5$. The construction is described in terms of geometry of

Regular star complements in strongly regular graphs [PDF]

open access: yes, 2012
We prove that, aside from the complete multipartite graphs and graphs of Steiner type, there are only finitely many connected strongly regular graphs with a regular star complement of prescribed degree s∈N.

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

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 ...

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

Fundamental relation on m-idempotent hyperrings

open access: yesOpen Mathematics, 2017
The γ*-relation defined on a general hyperring R is the smallest strongly regular relation such that the quotient R/γ* is a ring. In this note we consider a particular class of hyperrings, where we define a new equivalence, called εm∗$\varepsilon^{*}_{m}

Some results on the filter method for nonlinear complementary problems

open access: yesJournal of Inequalities and Applications, 2021
Recent studies show that the filter method has good numerical performance for nonlinear complementary problems (NCPs). Their approach is to reformulate an NCP as a constrained optimization solved by filter algorithms.
