Characterizing heavy subgraph pairs for pancyclicity [PDF]

open access: yes, 2015
Earlier results originating from Bedrossian’s PhD Thesis focus on characterizing pairs of forbidden subgraphs that imply hamiltonian properties. Instead of forbidding certain induced subgraphs, here we relax the requirements by imposing Ore-type degree ...

Forbidden Subgraphs for Hamiltonicity of 1-Tough Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2016
A graph G is said to be 1-tough if for every vertex cut S of G, the number of components of G − S does not exceed |S|. Being 1-tough is an obvious necessary condition for a graph to be hamiltonian, but it is not sufficient in general.

3-Colourability and Forbidden Subgraphs

open access: yesElectronic Notes in Discrete Mathematics, 2000
Abstract In this paper we investigate the chromatic aspects for graphs with forbidden induced subgraphs with emphasis on the question of 3-colourability. In the main part all possible pairs (A, B) of forbidden induced subgraphs, s.t. every A- and B -free graph is 3-colourable, are determined.

On the number of pentagons in triangle-free graphs [PDF]

open access: yes, 2013
Using the formalism of flag algebras, we prove that every triangle-free graph G with n vertices contains at most (n/5)(5) cycles of length five. Moreover, the equality is attained only when n is divisible by five and G is the balanced blow-up of the ...

Parallel Algorithms for the Subgraph Homeomorphism Problem

open access: yes, 1989
The subgraph homeomorphism problem for a fixed graph $H$ is stated as follows: given a graph $G$, determine whether $G$ has a subgraph homeomorphic to $H$, and obtain it.

Local certification of forbidden subgraphs

open access: yesCoRR
Detecting specific structures in a network has been a very active theme of research in distributed computing for at least a decade. In this paper, we start the study of subgraph detection from the perspective of local certification. Remember that a local certification is a distributed mechanism enabling the nodes of a network to check the correctness ...
