Given a holomorphic iterated function scheme with a finite symmetry group $G$, we show that the associated dynamical zeta function factorizes into symmetry-reduced analytic zeta functions that are parametrized by the unitary irreducible representations of $G$. We show that this factorization implies a factorization of the Selberg zeta function on symmetric $n$-funneled surfaces and that the symmetry factorization simplifies the numerical calculations of the resonances by several orders of… 
L-functions and sharp resonances of infinite index congruence subgroups of $SL_2(\mathbb{Z})$
For convex co-compact subgroups of SL2(Z) we consider the "congruence subgroups" for p prime. We prove a factorization formula for the Selberg zeta function in term of L-functions related to
Meromorphic Continuation of Weighted Zeta Functions on Open Hyperbolic Systems
In this article we prove meromorphic continuation of weighted zeta functions Zf in the framework of open hyperbolic systems by using the meromorphically continued restricted resolvent of Dyatlov and
Let Γ be a convex co-compact subgroup of SL2(Z) and consider the ”congruence subgroups” Γ(p) C Γ, for p prime. Let Xp := Γ(p)\H be the associated family of hyperbolic surfaces covering X := Γ\H, we
Spectral gaps without the pressure condition
For all convex co-compact hyperbolic surfaces, we prove the existence of an essential spectral gap, that is a strip beyond the unitarity axis in which the Selberg zeta function has only finitely many

In this paper we give an overview over some aspects of the modern mathematical theory of Ruelle resonances for chaotic, i.e. uniformly hyperbolic, dynamical systems and their implications in physics.

Let $\Gamma$ be a convex co-compact discrete group of isometries of the hyperbolic plane $\mathbb{H}^2$, and $X=\Gamma\backslash \mathbb{H}^2$ the associated surface. In this paper we investigate the
Global Normal Form and Asymptotic Spectral Gap for Open Partially Expanding Maps
We consider a $${\mathbb{R}}$$R-extension of one dimensional uniformly expanding open dynamical systems and prove a new explicit estimate for the asymptotic spectral gap. To get these results, we use
Resonance Chains and Geometric Limits on Schottky Surfaces
Resonance chains have been observed in many different physical and mathematical scattering problems. Recently, numerical studies linked the phenomenon of resonances chains to an approximate

Resonances for Open Quantum Maps and a Fractal Uncertainty Principle
We study eigenvalues of quantum open baker’s maps with trapped sets given by linear arithmetic Cantor sets of dimensions $${\delta\in (0,1)}$$δ∈(0,1). We show that the size of the spectral gap is


The divisor of Selberg's zeta function for Kleinian groups
We compute the divisor of Selberg's zeta function for convex co-compact, torsion-free discrete groups acting on a real hyperbolic space of dimension n + 1. The divisor is determined by the
The Selberg Zeta Function for Convex Co-Compact Schottky Groups
We give a new upper bound on the Selberg zeta function for a convex co-compact Schottky group acting on the hyperbolic space ℍn+1: in strips parallel to the imaginary axis the zeta function is
Symmetry decomposition of chaotic dynamics
Discrete symmetries of dynamical flows give rise to relations between periodic orbits, reduce the dynamics to a fundamental domain, and lead to factorizations of zeta functions. These factorizations
Resonance chains in open systems, generalized zeta functions and clustering of the length spectrum
In many non-integrable open systems in physics and mathematics, resonances have been found to be surprisingly ordered along curved lines in the complex plane. In this article we provide a unifying
Distribution of Resonances for Hyperbolic Surfaces
This work studies the distribution of resonances for geometrically finite hyperbolic surfaces of infinite area by counting resonances numerically and focuses on three aspects of the resonance distribution that have attracted attention recently: the fractal Weyl law, the spectral gap, and the concentration of decay rates.
Scattering asymptotics for Riemann surfaces
In this article we prove the optimal polynomial lower bound for the number of resonances of a surface with hyperbolic ends. We also give Weyl asymptotics for the relative scattering phase of such a
Zeta-functions for expanding maps and Anosov flows
Given a real-analytic expanding endomorphism of a compact manifoldM, a meromorphic zeta function is defined on the complex-valued real-analytic functions onM. A zeta function for Anosov flows is

Let $\Lambda$ be a non-elementary convex co-compact fuchsian group which is a subgroup of an arithmetic fuchsian group. We prove that the Laplace operator of the hyperbolic surface $X=\Lambda

For convex co-compact hyperbolic manifolds of even dimension n + 1, we derive a Poisson-type formula for scattering resonances which may be regarded as a version of Selberg's trace formula for these
