Query: Entropy geometry and disjointness for zero-dimensional algebraic actions   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.
