Quasipolynomiality of the Smallest Missing Induced Subgraph

open access: yes, 2023
We study the problem of finding the smallest graph that does not occur as an induced subgraph of a given graph. This missing induced subgraph has at most logarithmic size and can be found by a brute-force search, in an $n$-vertex graph, in time $n^{O ...

Polyhedral properties of the induced cluster subgraphs [PDF]

open access: yesDiscrete Applied Mathematics, 2021
A cluster graph is a graph whose every connected component is a complete graph. Given a simple undirected graph $G$, a subset of vertices inducing a cluster graph is called an independent union of cliques (IUC), and the IUC polytope associated with $G$ is defined as the convex hull of the incidence vectors of all IUCs in the graph. The {\sc Maximum IUC}

Reconfiguration of Regular Induced Subgraphs

open access: yes, 2022
We study the problem of checking the existence of a step-by-step transformation of $d$-regular induced subgraphs in a graph, where $d \ge 0$ and each step in the transformation must follow a fixed reconfiguration rule. Our problem for $d=0$ is equivalent to \textsc{Independent Set Reconfiguration}, which is one of the most well-studied reconfiguration ...

Induced Subgraphs of the Power of a Cycle [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 1989
In this article, it is shown that if G is an induced subgraph of the dth power of a cycle of length n, and G has minimum degree $d + k$, then G has at least $[ (d + k)/2d ]n$ vertices. This answers a problem of Kezdy.

Graphs containing finite induced paths of unbounded length [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2022
The age $\mathcal{A}(G)$ of a graph $G$ (undirected and without loops) is the collection of finite induced subgraphs of $G$, considered up to isomorphy and ordered by embeddability. It is well-quasi-ordered (wqo) for this order if it contains no infinite

Induced Subgraphs and Path Decompositions

open access: yesThe Electronic Journal of Combinatorics, 2023
A graph $H$ is an induced subgraph of a graph $G$ if a graph isomorphic to $H$ can be obtained from $G$ by deleting vertices. Recently, there has been significant interest in understanding the unavoidable induced subgraphs for graphs of large treewidth.

The line completion number of hypercubes

open access: yesAKCE International Journal of Graphs and Combinatorics, 2019
In 1992, Bagga, Beineke, and Varma introduced the concept of the super line graph of index of a graph denoted by The vertices of are the -subsets of and two vertices and are adjacent if there exist and such that and are adjacent edges in They also ...
