Reconfiguration of vertex colouring and forbidden induced subgraphs [PDF]

open access: yesEuropean Journal of Combinatorics, 2022
The reconfiguration graph of the $k$-colourings, denoted $\mathcal{R}_k(G)$, is the graph whose vertices are the $k$-colourings of $G$ and two colourings are adjacent in $\mathcal{R}_k(G)$ if they differ in colour on exactly one vertex. In this paper, we

Complexity Dichotomy for List-5-Coloring with a Forbidden Induced Subgraph [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2021
For a positive integer $r$ and graphs $G$ and $H$, we denote by $G+H$ the disjoint union of $G$ and $H$, and by $rH$ the union of $r$ mutually disjoint copies of $H$. Also, we say $G$ is $H$-free if $H$ is not isomorphic to an induced subgraph of $G$. We

Forbidden induced subgraph characterization of circle graphs within split graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2020
A graph is circle if its vertices are in correspondence with a family of chords in a circle in such a way that every two distinct vertices are adjacent if and only if the corresponding chords have nonempty intersection.

Forbidden Induced Subgraphs [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2016
In descending generality I survey: five partial orderings of graphs, the induced-subgraph ordering, and examples like perfect, threshold, and mock threshold graphs. The emphasis is on how the induced subgraph ordering differs from other popular orderings

Line Graphs and Forbidden Induced Subgraphs [PDF]

open access: yesJournal of Combinatorial Theory, Series B, 2001
Beineke and Robertson independently characterized line graphs in terms of nine forbidden induced subgraphs. In 1994, Šoltés gave another characterization, which reduces the number of forbidden induced subgraphs to seven, with only five exceptional cases.

Large homogeneous subgraphs in bipartite graphs with forbidden induced subgraphs [PDF]

open access: yesJournal of Graph Theory, 2019
For a bipartite graph G , let h ˜ ( G ) be the largest t such that either G contains K t , t , a complete bipartite subgraph with parts of size t , or the bipartite complement of G contains K t , t as a subgraph. For a class of graphs F , let h ˜ ( F ) =

Hitting forbidden induced subgraphs on bounded treewidth graphs [PDF]

open access: yesInformation and Computation, 2020
For a fixed graph $H$, the $H$-IS-Deletion problem asks, given a graph $G$, for the minimum size of a set $S \subseteq V(G)$ such that $G\setminus S$ does not contain $H$ as an induced subgraph.

Path Eccentricity and Forbidden Induced Subgraphs

open access: yesCoRR
The path eccentricity of a connected graph $G$ is the minimum integer $k$ such that $G$ has a path such that every vertex is at distance at most $k$ from the path.
