随机动力系统的局部熵理论

Local Entropy Theory of a Random Dynamical System

Anthony H. Dooley, Guohua Zhang

摘要:

本文将连续丛随机动力系统的概念推广到$\R$或$\N$的作用被无限可数离散顺从群的作用所取代的情形。给定这样一个系统和一个单调次可加不变随机连续函数族,我们引入了局部纤维拓扑压力的概念,并建立了一个相关的变分原理,将其与测度论熵联系起来.我们还讨论了这个变分原理的一些变形。我们引入连续丛随机动力系统的拓扑和测度熵元组,并应用我们的变分原理来获得这些熵元组之间的关系。最后,我们将这些结果应用到一般的拓扑动力系统中,恢复和推广了局部熵理论中的许多新结果。

英文摘要:

In this paper we extend the notion of a continuous bundle random dynamical system to the setting where the action of $\R$ or $\N$ 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, we introduce the concept of local fiber topological pressure and establish an associated variational principle, relating it to measure-theoretic entropy. We also discuss some variants of this variational principle. We introduce both topological and measure-theoretic entropy tuples for continuous bundle random dynamical systems, and apply our variational principles to obtain a relationship between these of entropy tuples. Finally, we give applications of these results to general topological dynamical systems, recovering and extending many recent results in local entropy theory.
