Entropy geometry and disjointness for zero-dimensional algebraic actions

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/98499We 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.21 page latexDynamical SystemsGeometric Topology22D40; 37A15; 52B11Entropy geometry and disjointness for zero-dimensional algebraic actionstext
