接触Anosov流中球直径的正则衰减和Ruelle算子的谱

Regular decay of ball diameters and spectra of Ruelle operators for contact Anosov flows

Luchezar Stoyanov

摘要:

对于紧致Riemann流形上的Anosov流,我们研究了局部稳定流形上的球直径$B^s(x,\ep)$在Lyapunov正则点$x$处沿流的衰减率.我们证明,这种衰减率是相似的所有足够小的值的$ε> 0$。从这个和\cite{kn:St1}的主要结果,我们得到强谱估计的Ruelle转移算子接触Anosov流Lipschitz局部稳定holonomy映射。这些特别适用于严格负曲率的紧致局部对称流形上的测地流。众所周知,这种谱估计在某些相关领域有着深远的意义,例如在研究Ruelle zeta函数和偏微分算子的解析性质,闭轨道计数函数的渐近性等方面。

英文摘要:

For Anosov flows on compact Riemann manifolds we study the rate of decay along the flow of diameters of balls $B^s(x,\ep)$ on local stable manifolds at Lyapunov regular points $x$. We prove that this decay rate is similar for all sufficiently small values of $ε> 0$. From this and the main result in \cite{kn:St1}, we derive strong spectral estimates for Ruelle transfer operators for contact Anosov flows with Lipschitz local stable holonomy maps. These apply in particular to geodesic flows on compact locally symmetric manifolds of strictly negative curvature. As is now well known, such spectral estimates have deep implications in some related areas, e.g. in studying analytic properties of Ruelle zeta functions and partial differential operators, asymptotics of closed orbit counting functions, etc.
