Abstract

In 1998, Burago-Kleiner and McMullen independently proved the existence of separated nets in Rd\mathbb{R}^d which are not bi-Lipschitz equivalent (BL) to a lattice. A finer equivalence relation than BL is bounded displacement (BD). Separated nets arise naturally as return times to a section for minimal Rd\mathbb{R}^d-actions. We analyze the separated nets which arise via these constructions, focusing particularly on nets arising from linear Rd\mathbb{R}^d-actions on tori. We show that generically these nets are BL to a lattice, and for some choices of dimensions and sections, they are generically BD to a lattice. We also show the existence of such nets which are not BD to a lattice.
