一类部分双曲型方程组稳定遍历性的$C^{r}-$普遍性

$C^{r}-$prevalence of stable ergodicity for a class of partially hyperbolic systems

Martin Leguil, Zhiyuan Zhang

摘要:

本文证明了对$r \in \mathbb{N}_{\geq 2} \cup \{\infty\}$,对任意动力相干的中心聚束的强压缩的保体积的部分双曲双曲同胚$C^r$,如果(1)它的中心叶理是一致紧的,或(2)它的中心稳定叶理和中心不稳定叶理是$C^1$类的,则在${\rm Diff}^r(X,\mathrm{Vol})$中存在$f$的$C^1$ -开邻域,其中稳定遍历性在Kolmogorov意义上是$C^r$ -普遍的。特别地,我们验证了Pugh-Shub的稳定遍历猜想在这个区域。这也提供了第一个结果,验证了普遍的稳定遍历性的测度理论意义。我们的定理适用于一大类代数系统。作为应用,我们在强箍缩区域肯定地回答了:1。Pugh-Shub在\cite{PS}中的一个未决问题; 2. \cite{HPS}中Hirsch-Pugh-Shub开放性问题的通用版本;以及3. \cite{HPS}中Pugh-Shub开放性问题的通用版本。

英文摘要:

We prove that for $r \in \mathbb{N}_{\geq 2} \cup \{\infty\}$, for any dynamically coherent, center bunched and strongly pinched volume preserving $C^r$ partially hyperbolic diffeomorphism $f \colon X \to X$, if either (1) its center foliation is uniformly compact, or (2) its center-stable and center-unstable foliations are of class $C^1$, then there exists a $C^1$-open neighbourhood of $f$ in ${\rm Diff}^r(X,\mathrm{Vol})$, in which stable ergodicity is $C^r$-prevalent in Kolmogorov's sense. In particular, we verify Pugh-Shub's stable ergodicity conjecture in this region. This also provides the first result that verifies the prevalence of stable ergodicity in the measure-theoretical sense. Our theorem applies to a large class of algebraic systems. As applications, we give affirmative answers in the strongly pinched region to: 1. an open question of Pugh-Shub in \cite{PS}; 2. a generic version of an open question of Hirsch-Pugh-Shub in \cite{HPS}; and 3. a generic version of an open question of Pugh-Shub in \cite{HPS}.
