Entropy geometry and disjointness for zero-dimensional algebraic actions

Dynamical Systems 2007-05-23 v1 Geometric Topology

Abstract

We show that many algebraic actions of higher-rank abelian groups on zero-dimensional groups are mutually disjoint. The proofs exploit differences in the entropy geometry arising from subdynamics and a form of Abramov--Rokhlin formula for half-space entropies.
