High-intensity Voronoi percolation on manifolds (2503.21737v1)

Abstract: We study Voronoi percolation on a large class of $d$-dimensional Riemannian manifolds, which includes hyperbolic space $\mathbb{H}^d$ for $d\geq 2$. We prove that as the intensity $\lambda$ of the underlying Poisson point process tends to infinity, both critical parameters $p_c(M,\lambda)$ and $p_u(M,\lambda)$ converge to the Euclidean critical parameter $p_c(\mathbb{R}^d)$. This extends a recent result of Hansen & M\"uller in the special case $M=\mathbb{H}^2$ to a general class of manifolds of arbitrary dimension. A crucial step in our proof, which may be of independent interest, is to show that if $M$ is simply connected and one-ended, then embedded graphs induced by a general class of tessellations on $M$ have connected minimal cutsets. In particular, this result applies to $\varepsilon$-nets, allowing us to implement a "fine-graining" argument. We also develop an annealed way of exploring the Voronoi cells that we use to characterize the uniqueness phase.
