A Profinite Module associated to a hyperbolic toral automorphism
In this talk we describe and discuss some of the properties of a profinite module associated to a hyperbolic toral automorphism, defined by its action on periodic orbits. We are particularly interested in understanding to what extent the algebraic/topological classification of those automorphisms is determined by that action.
