Abstract

The well-known Erdős-Hajnal conjecture states that for any graph H, there is a constant c=c(H)>0 such that every n-vertex graph G with no induced copies of H contains a clique or an independent set of size at least nc. In this paper, we prove that the Erdős-Hajnal conjecture holds for every path.
