Pure pairs. IV. Trees in bipartite graphs

Abstract:
In this paper we investigate the bipartite analogue of the strong Erdős-Hajnal property. We prove that for every forest H and every τ with 0 < τ ≤ 1, there exists ε > 0, such that if G has a bipartition (A, B) and does not contain H as an induced subgraph, and has at most (1 − τ)|A| · |B| edges, then there is a stable set X of G with |X ∩ A| ≥ ε|A| and |X∩B| ≥ ε|B|. No graphs H except forests have this property
