Continuum-wise expansiveness and specification for set-valued functions and topological entropy

Dynamical Systems 2015-10-27 v1

Abstract

We define the concept of continuum wise expansive for set-valued functions and prove that if a compact metric space admit a set-valued cwcw-expansive function then the topological entropy of XX is positive.} We also introduce the notion of pointwise specification property for set-valued functions and prove that set-valued functions with this property has positive entropy.
