非一致展开非自治离散系统的遍历性

Ergodicity of non-autonomous discrete systems with non-uniform expansion

Pablo G. Barrientos, Abbas Fakhari

摘要:

研究具有非一致展开的非自治离散动力系统的遍历性。作为应用,我们得到了紧致流形上的$C^{1+α}$局部单同态的任何一致扩张的单生成半群作用关于勒贝格测度是遍历的.此外,我们还证明了紧致流形上的共形$C^{1+α}$局部超同态的每一个精确非一致可扩张超同构生成半群作用是Lebesgue遍历的。

英文摘要:

We study the ergodicity of non-autonomous discrete dynamical systems with non-uniform expansion. As an application we get that any uniformly expanding finitely generated semigroup action of $C^{1+α}$ local diffeomorphisms of a compact manifold is ergodic with respect to the Lebesgue measure. Moreover, we will also prove that every exact non-uniform expandable finitely generated semigroup action of conformal $C^{1+α}$ local diffeomorphisms of a compact manifold is Lebesgue ergodic.
