Topological speedups of $\mathbb{Z}^d$-actions

Dynamical Systems 2021-03-04 v1

Abstract

We study minimal Zd\mathbb{Z}^d-Cantor systems and the relationship between their speedups, their collections of invariant Borel measures, their associated unital dimension groups, and their orbit equivalence classes. In the particular case of minimal Zd\mathbb{Z}^d-odometers, we show that their bounded speedups must again be odometers but, contrary to the 1-dimensional case, they need not be conjugate, or even isomorphic, to the original.
