# Local Entropy Theory of a Random Dynamical System

Share this page
*Anthony H. Dooley; Guohua Zhang*

In this paper the authors extend the notion of a continuous
bundle random dynamical system to the setting where the action of
\(\mathbb{R}\) or \(\mathbb{N}\) is replaced by the
action of an infinite countable discrete amenable group.

Given such a system, and a monotone sub-additive invariant family
of random continuous functions, they introduce the concept of local
fiber topological pressure and establish an associated variational
principle, relating it to measure-theoretic entropy. They also discuss
some variants of this variational principle.

The authors introduce both topological and measure-theoretic entropy tuples
for continuous bundle random dynamical systems, and apply
variational principles to obtain a relationship between these of
entropy tuples. Finally, they give applications of these results to
general topological dynamical systems, recovering and extending many
recent results in local entropy theory.
