Abstract

In this paper, we introduce the notion of k-centerpoints for any set P of n points in Rd. These unify and generalize previous results such as the classical centerpoint theorem,1 and the recently-proven ray-shooting theorem.2 We define two variants: affine k-centerpoints, and topological k-centerpoints. We prove their equivalence in R2, and conjecture that these are in fact equivalent in any dimension. We present the first non-trivial bounds for these problems in Rd, as well as present several conjectures related to them.
