A resolution of the Gaussian hyperplane tessellation conjecture on the sphere

Probability 2025-08-08 v1

Abstract

We investigate how many hyperplanes with independent standard Gaussian directions one needs to produce a δ\delta-uniform tessellation of a subset SS of the Euclidean sphere, meaning that for any pair of points in SS the fraction of hyperplanes separating them corresponds to their geodesic distance up to an additive error δ\delta. It was conjectured that δ2w(S)2\delta^{-2}w_*(S)^2 Gaussian random hyperplanes are necessary and sufficient for this purpose, where w(S)w_*(S) is the Gaussian complexity of SS. We falsify this conjecture by constructing a set SS where δ3w(S)2\delta^{-3}w_*(S)^2 Gaussian hyperplanes are necessary and sufficient.
