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

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

Ratio 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

On the nature and origin of consumer vulnerability [PDF]
Anali 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 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
Journal 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.

A Strong Regular Relation on ?-Semihyperrings [PDF]
Journal of Sciences, Islamic Republic of Iran, 2011 The concept of algebraic hyperstructures introduced by Marty as a generalization of ordinary algebraic structures. In an ordinary algebraic structure, the composition of two elements is an element, while in an algebraic hyperstructure, the composition of

Regularity of Intuitionistic Fuzzy Relations on Hypergroupoids
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 In this paper we introduce the notions of regular and strongly regular intuitionistic fuzzy relations on hypergroupoids, studying some related properties and connections with the classical case. Then we investigate the lattice structure of these kinds of

Characterizations of (strongly) ordered regular relations on ordered semihypergroups
Journal of Algebra, 2016 In this paper, the authors study the concept of ordered regular (strongly ordered regular) equivalence relations on ordered semihypergroups. In particular, they construct an ordered regular equivalence relation on an ordered semihypergroup by hyperideals such that the corresponding quotient structure is also an ordered semihypergroup, which answers the
