Partial product of graphs and Vizing's conjecture

open access: yesArs Mathematica Contemporanea, 2014
Let G and H be two graphs with vertex sets V 1  = { u 1 , . . . ,  u n 1 } and V 2  = { v 1 , . . . ,  v n 2 } , respectively. If S  ⊂  V 2 , then the partial Cartesian product of G and H with respect to S is the graph G □ S H  = ( V ,  E ) , where V  =  V 1  ×  V 2 and two vertices ( u i ,  v j

Vizing's 2-Factor Conjecture Involving Toughness and Maximum Degree Conditions

open access: yesThe Electronic Journal of Combinatorics, 2019
Let $G$ be a simple graph, and let $\Delta(G)$ and $\chi'(G)$ denote the maximum degree and chromatic index of $G$, respectively. Vizing proved that $\chi'(G)=\Delta(G)$ or $\chi'(G)=\Delta(G)+1$. We say $G$ is $\Delta$-critical if $\chi'(G)=\Delta(G)+1$ and $\chi'(H)<\chi'(G)$ for every proper subgraph $H$ of $G$.

Clinicians' Assessment of Antisocial Personality Disorder (ASPD): A Network Analysis Approach on DSM‐5‐TR Criteria and Domains

open access: yesPersonality and Mental Health, Volume 19, Issue 2, May 2025.
ABSTRACT Antisocial Personality Disorder (ASPD) is a personality disorder that entails significant impairments and/or costs at the individual, interpersonal, and community levels. Given its clinical relevance, scientific research is placing a significant focus on the study of the central characteristics of this condition to guide prevention and ...

Parameters related to fractional domination in graphs. [PDF]

open access: yes, 1995
Thesis (M.Sc.)-University of Natal, 1995.The use of characteristic functions to represent well-known sets in graph theory such as dominating, irredundant, independent, covering and packing sets - leads naturally to fractional versions of these sets and ...

Essentially tight bounds for rainbow cycles in proper edge‐colourings

open access: yesProceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.
Abstract An edge‐coloured graph is said to be rainbow if no colour appears more than once. Extremal problems involving rainbow objects have been a focus of much research over the last decade as they capture the essence of a number of interesting problems in a variety of areas.

Central limit theorem in disordered Monomer‐Dimer model

open access: yesRandom Structures &Algorithms, Volume 66, Issue 1, January 2025.
Abstract We consider the disordered monomer‐dimer model on general finite graphs with bounded degrees. Under the finite fourth moment assumption on the weight distributions, we prove a Gaussian central limit theorem for the free energy of the associated Gibbs measure with a rate of convergence. The central limit theorem continues to hold under a nearly

Unmasking the Dark Triad: A Data Fusion Machine Learning Approach to Characterize the Neural Bases of Narcissistic, Machiavellian and Psychopathic Traits

open access: yesEuropean Journal of Neuroscience, Volume 61, Issue 2, January 2025.
ABSTRACT The Dark Triad (DT), encompassing narcissism, Machiavellianism and psychopathy traits, poses significant societal challenges. Understanding the neural underpinnings of these traits is crucial for developing effective interventions and preventive strategies. Our study aimed to unveil the neural substrates of the DT by examining brain scans from

Proof of the Goldberg-Seymour Conjecture on Edge-Colorings of Multigraphs

open access: yes, 2019
Given a multigraph $G=(V,E)$, the {\em edge-coloring problem} (ECP) is to color the edges of $G$ with the minimum number of colors so that no two adjacent edges have the same color.
