非紧集的自由半群作用的拓扑压与Bowen方程

Topological pressure of free semigroup actions for non-compact sets and Bowen's equation

Qian Xiao, Dongkui Ma

摘要:

Climenhaga证明了Bowen方程对紧度量空间的任意子集的适用性。本文的主要目的是将Climenhaga的主要结果推广到非紧集的自由半群作用。利用Caratheodory-Pesin结构,引入了非紧集上自由半群作用的拓扑压和上、下容量拓扑压的概念.这些概念的一些属性,其次是三个主要结果。一种方法是利用Bowen方程刻画任意子集的豪斯多夫维数,其点具有正的下李雅普诺夫指数且满足缓和压缩条件,二是自由半群作用在X的任意子集上的拓扑压的估计;三是斜-乘积变换和自由半群作用关于任意子集的上容量拓扑压。

英文摘要:

Climenhaga showed the applicability of Bowen equation to arbitrary subset of a compact metric space. The main purpose of this paper is to generalize the main result of Climenhaga to free semigroup actions for non-compact sets. We introduce the notions of the topological pressure and lower and upper capacity topological pressure of a free semigroup action for non-compact sets by using the Caratheodory- Pesin structure. Some properties of these notions are given, followed by three main results. One is to characterize the Hausdorff dimension of arbitrary subset in term of the topological pressure by Bowen equation, whose points have the positive lower Lyapunov exponents and satisfy a tempered contraction condition, the other is the estimation of topological pressure of a free semigroup action on arbitrary subset of X and the third is the relationship between the upper capacity topological pressure of a skew-product transformation and the upper capacity topological pressure of a free semigroup action with respect to arbitrary subset.
