摘要:

本文考虑一类丰富的非一致双曲$C^2$ -Hénon型强正则的类同态,它对应于Benedicks-Carleson参数.证明了$m>0$的存在性,使得对于任何这样的双同态$f$,$f$的每个不变概率测度的李雅普诺夫指数大于$m$,回答了L.卡尔森此外,我们还证明了极大熵测度的存在唯一性,从而回答了M. Lyubich和Y. Pesin.我们还证明了极大熵测度在周期点上是等分布的,并且是有限的Bernoulli,从而回答了J. P.最后,我们证明了极大熵测度是指数混合的,并且满足中心极限定理。证明是基于一个新的构造的杨塔的第一个返回时间与符号返回时间相一致,其轨道是共轭的强正经常性马尔可夫移动。

英文摘要:

We consider an abundant class of non-uniformly hyperbolic $C^2$-Hénon like diffeomorphisms called strongly regular and which corresponds to Benedicks-Carleson parameters. We prove the existence of $m>0$ such that for any such diffeomorphism $f$, every invariant probability measure of $f$ has a Lyapunov exponent greater than $m$, answering a question of L. Carleson. Moreover, we show the existence and uniqueness of a measure of maximal entropy, this answers a question of M. Lyubich and Y. Pesin. We also prove that the maximal entropy measure is equi-distributed on the periodic points and is finitarily Bernoulli, which gives an answer to a question of J.P. Thouvenot. Finally, we show that the maximal entropy measure is exponentially mixing and satisfies the central limit Theorem. The proof is based on a new construction of Young tower for which the first return time coincides with the symbolic return time, and whose orbit is conjugated to a strongly positive recurrent Markov shift.
