关于部分双曲动力系统的非零中心李雅普诺夫指数、物理测度和稳定遍历性

On the abundance of non-zero central Lyapunov exponents, physical measures and stable ergodicity for partially hyperbolic dynamics

Vitor Araujo, Carlos H. Vasquez

摘要:

我们表明,时间-1地图的Anosov流,其强不稳定的叶理是$C^2$光滑和最小的,是$C^2$接近一个具有正的中心李雅普诺夫指数勒贝格几乎处处和一个独特的物理措施,与完整的盆地,这是$C^r$稳定遍历的一个自同构。我们的方法是微扰的,并不依赖于保持一个光滑的措施。

英文摘要:

We show that the time-1 map of an Anosov flow, whose strong-unstable foliation is $C^2$ smooth and minimal, is $C^2$ close to a diffeomorphism having positive central Lyapunov exponent Lebesgue almost everywhere and a unique physical measure with full basin, which is $C^r$ stably ergodic. Our method is perturbative and does not rely on preservation of a smooth measure.
