Abstract

An ordered partition of a set of n points in the d-dimensional Euclidean space is called a separable partition if the convex hulls of the parts are pairwise disjoint. For each fixed p and d we determine the maximum possible number r_p,d(n) of separable partitions into p parts of n points in real d-space up to a constant factor. Of particular interest are the values r_p,d(n) = Θ(n^d(2p)) for every fixed p and d ≥ 3. and r_p,2(n) = Θ(n^6p-12) for every fixed p ≥ 3. We establish similar results for spaces of finite Vapnik-Chervonenkis dimension and study the corresponding problem for points on the moment curve as well.

N2 - An ordered partition of a set of n points in the d-dimensional Euclidean space is called a separable partition if the convex hulls of the parts are pairwise disjoint. For each fixed p and d we determine the maximum possible number rp,d(n) of separable partitions into p parts of n points in real d-space up to a constant factor. Of particular interest are the values rp,d(n) = Θ(nd(2p)) for every fixed p and d ≥ 3. and rp,2(n) = Θ(n6p-12) for every fixed p ≥ 3. We establish similar results for spaces of finite Vapnik-Chervonenkis dimension and study the corresponding problem for points on the moment curve as well.
