On crossing families of complete geometric graphs

A crossing family is a collection of pairwise crossing segments, this concept was introduced by Aronov et al. [4]. They proved that any set of n points (in general position) in the plain contains a crossing family of size \({\sqrt{n/12}}\). In this paper we present a generalization of the concept and give several results regarding this generalization.
