Improved bounds for geometric permutations

Research output: Contribution to journalArticlepeer-review

Abstract

We show that the number of geometric permutations of an arbitrary collection of n pairwise disjoint convex sets in Rd, for d = 3, is O(n2d-3 log n), improving Wenger's 20-year-old bound of O(n2d-2).
