K-sets in four dimensions

Jiri Matousek, Micha Sharir, Shakhar Smorodinsky, Uli Wagner

We show, with an elementary proof, that the number of halving simplices in a set of n points in 4 in general position is O(n4-2/45). This improves the previous bound of O(n4-1/134). Our main new ingredient is a bound on the maximum number of halving simplices intersecting a fixed 2-plane.
