Forbidden induced subgraphs for toughness
J. Graph Theory, 2013Summary: Let \(\mathcal F\) be a family of connected graphs. A graph \(G\) is said to be \(\mathcal F\)-free if \(G\) is \(H\)-free for every graph \(H\) in \(\mathcal F\). We study the relation between forbidden subgraphs in a connected graph \(G\) and the resulting toughness of \(G\). In particular, we consider the problem of characterizing the graph

Forbidden induced subgraph characterization of cograph contractions
Journal of Graph Theory, 2004AbstractLet S1, S2,…,St be pairwise disjoint non‐empty stable sets in a graph H. The graph H* is obtained from H by: (i) replacing each Si by a new vertex qi; (ii) joining each qi and qj, 1 ≤ i # j ≤ t, and; (iii) joining qi to all vertices in H – (S1 ∪ S2 ∪ ··· ∪ St) which were adjacent to some vertex of Si. A cograph is a P4‐free graph.

Hereditary Domination in Graphs: Characterization with Forbidden Induced Subgraphs
SIAM Journal on Discrete Mathematics, 2008The leaf graph of a connected graph is obtained by joining a new vertex of degree one to each noncutting vertex. We prove that if a connected graph $G$ is not dominated by any of its induced paths, then $G$ is dominated by a connected induced subgraph whose leaf graph, too, is an induced subgraph of $G$. It follows that, for every nonempty class ${\cal

Complexity of Coloring Graphs without Forbidden Induced Subgraphs
2001We give a complete characterization of parameter graphs H for which the problem of coloring H-free graphs is polynomial and for which it is NP-complete. We further initiate a study of this problem for two forbidden subgraphs.
