$2$ -环面的Anosov同态的非稠密轨道

Nondense orbits for Anosov diffeomorphisms of the $2$-torus

Jimmy Tseng

摘要:

令$λ$表示${\mathbb T}^2$上的概率勒贝格测度。对于测度熵等于拓扑熵的保$λ$的$2$ -环面的任何$C^2$ -Anosov同构,我们证明了具有非稠密轨道的点集是超平面绝对获胜(HAW).这推广了~ \cite [定理~1.4]{T4}中关于圆的$C^2$ -扩张映射的结果.

英文摘要:

Let $λ$ denote the probability Lebesgue measure on ${\mathbb T}^2$. For any $C^2$-Anosov diffeomorphism of the $2$-torus preserving $λ$ with measure-theoretic entropy equal to topological entropy, we show that the set of points with nondense orbits is hyperplane absolute winning (HAW). This generalizes the result in~\cite[Theorem~1.4]{T4} for $C^2$-expanding maps of the circle.
