Radovanović, M, Trotignon, N and Vuskovic, K (2021) The (theta, wheel)-free graphs Part IV: Induced paths and cycles. Journal of Combinatorial Theory: Series B, 146. pp. 495-531. ISSN 0095-8956
Abstract
A hole in a graph is a chordless cycle of length at least 4. A theta is a graph formed by three internally vertex-disjoint paths of length at least 2 between the same pair of distinct vertices. A wheel is a graph formed by a hole and a node that has at least 3 neighbors in the hole. In this series of papers we study the class of graphs that do not contain as an induced subgraph a theta nor a wheel. In Part II of the series we prove a decomposition theorem for this class, that uses clique cutsets and 2-joins. In this paper we use this decomposition theorem to solve several problems related to finding induced paths and cycles in our class.
