Abstract

It is known that the class of all graphs not containing a graph HH as an induced subgraph is cop-bounded if and only if HH is a forest whose every component is a path. In this study, we characterize all sets H\mathscr{H} of graphs with some kNk\in \mathbb{N} bounding the diameter of members of H\mathscr{H} from above, such that H\mathscr{H}-free graphs, i.e. graphs with no member of H\mathscr{H} as an induced subgraph, are cop-bounded. This, in particular, gives a characterization of cop-bounded classes of graphs defined by a finite set of connected graphs as forbidden induced subgraphs. Furthermore, we extend our characterization to the case of cop-bounded classes of graphs defined by a set H\mathscr{H} of forbidden graphs such that there is kNk\in\mathbb{N} bounding the diameter of components of members of H\mathscr{H} from above.
