Dynamics of the $p$-adic Shift and Applications

Abstract

We present a novel way of realizing the Bernoulli shift on $p$ symbols on the $p$-adic integers, where $p$ is a prime. By showing that suitably small perturbations of the shift are still Bernoulli we find many "nice" maps, such as polynomials on ${\mathbb{Z}}_p$, that are isomorphic to the (noninvertible) Bernoulli shift.
