闭流形上的整圈平均与迁移算子

Horocycle averages on closed manifolds and transfer operators

Alexander Adam, Viviane Baladi

摘要:

我们适应$C^r$ Anosov流紧流形上的$C^r$离散时间双曲动力系统($r>1$)的建设,获得各向异性的Banach或希尔伯特空间上的加权转移算子的生成元的预解式是拟紧的。应用这一方法研究了$C^r$余维1混合Anosov流的等循环流$h_ρ$的遍历积分.在三维空间中,对于任意适当聚束的具有可定向强稳定分布的$C^3$ Contact Anosov流,我们建立了遍历平均的幂律收敛性。因此,我们实现了朱利叶蒂-利维拉尼的程序中的“现实生活中的设置”的测地流在可变的负曲率,其中存在非平凡的共振。

英文摘要:

We adapt to $C^r$ Anosov flows on compact manifolds a construction for $C^r$ discrete-time hyperbolic dynamics ($r>1$), obtaining anisotropic Banach or Hilbert spaces on which the resolvent of the generator of weighted transfer operators for the flow is quasi-compact. We apply this to study the ergodic integrals of the horocycle flows $h_ρ$ of $C^r$ codimension one mixing Anosov flows. In dimension three, for any suitably bunched $C^3$ contact Anosov flow with orientable strong-stable distribution, we establish power-law convergence of the ergodic average. We thereby implement the program of Giulietti-Liverani in the "real-life setting" of geodesic flows in variable negative curvature, where nontrivial resonances exist.
