Abstract

Let G be a geometric graph on n vertices in general position in the plane. Suppose that for every line ℓ in the plane the subgraph of G induced by the set of vertices in one of the two half-planes bounded by ℓ has at most k edges (k<1 may be a function of n). Then G has at most O(nk) edges. This bound is best possible.
