## Improved bounds for geometric permutations in higher dimensions

I will present an improved bound of O(n3\log n) on the number of geometric permutations of a set of n arbitrary pairwise disjoint compact convex sets in three dimensions, which is the first improvement over Wenger's general bound from 1990. The result extends to higher dimensions too.

Joint work with Natan Rubin and Haim Kaplan.
