ON ERGODIC BEHAVIOR OF p-ADIC DYNAMICAL SYSTEMS

Abstract

Monomial mappings, x ↦ x n , are topologically transitive and ergodic with respect to Haar measure on the unit circle in the complex plane. In this paper we obtain an analogous result for monomial dynamical systems over p-adic numbers. The process is, however, not straightforward. The result will depend on the natural number n. Moreover, in the p-adic case we will not have ergodicity on the unit circle, but on the circles around the point 1.
