Positive entropy through pointwise dynamics

Author:

Arbieto A.,Rego E.

Abstract

We define some pointwise properties of topological dynamical systems and give pointwise conditions to guarantee the positiveness of the topological entropy of such a system. We also give sufficient conditions to obtain positive topological entropy for maps which are approximated by maps with the shadowing property in a uniform way.
