Abstract

We consider an extremal problem for directed graphs which is closely related to Turán's theorem giving the maximum number of edges in a graph on n vertices which does not contain a complete subgraph on mvertices. For an integer n⩾2, let Tn denote the transitive tournament with vertex set Xn={1,2,3,…,n} and edge set {(i,j):1⩽i
