Dolgopyat type estimates for pinched open billiard flows (Revised)

In this paper we consider open billiard flows in Euclidean spaces with C^1 (un)stable laminations over their non-wandering sets. We show that for such billiard flows the standard symplectic form satisfies a specific non-degeneracy condition over the non-wandering set. This allows to use some previous general results and obtain Dolgopyat type estimates for spectra of Ruelle transfer operators under simpler conditions. We also describe a class of open billiard flows in Euclidean spaces satisfying a certain pinching condition, which in turn implies that the (un)stable laminations over the non-wan…

Pollicott-Ruelle resonances for open systems

We define Pollicott-Ruelle resonances for geodesic flows on noncompact asymptotically hyperbolic negatively curved manifolds, as well as for more general open hyperbolic systems related to Axiom A flows. These resonances are the poles of the meromorphic continuation of the resolvent of the generator of the flow and they describe decay of classical correlations. As an application, we show that the Ruelle zeta function extends meromorphically to the entire complex plane.

Spectral estimates for Ruelle transfer operators with two parameters and applications

For $C^2$ weak mixing Axiom A flow $ϕ_t: M \longrightarrow M$ on a Riemannian manifold $M$ and a basic set $Λ$ for $ϕ_t$ we consider the Ruelle transfer operator $L_{f - s τ+ z g}$, where $f$ and $g$ are real-valued Hölder functions on $Λ$, $τ$ is the roof function and $s, z$ are complex parameters. Under some assumptions about $ϕ_t$ we establish estimates for the iterations of this Ruelle operator in the spirit of the estimates for operators with one complex parameter (see \cite{D}, \cite{St2}, \cite{St3}). Two cases are covered: (i) for arbitrary Hölder $f,g$ when $|\Im z| \leq B |\Im s|^μ$ …

Dynamical zeta functions for Axiom A flows

We show that the Ruelle zeta function of any smooth Axiom A flow with orientable stable/unstable spaces has a meromorphic continuation to the entire complex plane. The proof uses the meromorphic continuation result of [arXiv:1410.5516] together with the work of Conley-Easton and [arXiv:1711.10059] which imply that every basic hyperbolic set can be put into the framework of [arXiv:1410.5516].
