In this paper we study the distribution properties of periodic orbits for the linear hyperbolic automorphisms of the d-torus. We first obtain an explicit expression of the dynamical zeta function and prove general equidistribution results similar to those obtained for axiom A flows. We then study in detail some families of periodic orbits living on invariant prime lattices: they have the property that the integral of any character along any single orbit can be reduced to a number theoretic exponential sum over a finite field. This fact enables us to obtain explicit estimates on their asymptotic distributional properties.

Abstract
In this paper we study the distribution properties of periodic orbits for the linear hyperbolic automorphisms of the d-torus. We first obtain an explicit expression of the dynamical zeta function and prove general equidistribution results similar to those obtained for axiom A flows. We then study in detail some families of periodic orbits living on invariant prime lattices: they have the property that the integral of any character along any single orbit can be reduced to a number theoretic exponential sum over a finite field. This fact enables us to obtain explicit estimates on their asymptotic distributional properties.File in questo prodotto:
