The set of different cycle lengths of a graph G is denoted by C ( G ). We study how the distribution of C ( G ) depends on the minimum degree of G . We prove two results indicating that C ( G ) is dense in some sense. These results lead to the solution of a conjecture of Erdös and Hajnal stating that for suitable positive constants a, b the following holds:where δ( G ) denotes the minimum degree of G .
