We compute the divisor of Selberg's zeta function for convex cocompact, torsionfree discrete groups ; acting on a real hyperbolic space of dimension n +1. The divisor is determined by the eigenvalues and scattering poles of the Laplacian on X = ;nH n+1 together with the Euler characteristic of X compactified to a manifold with boundary.Ifn is even, the singularities of the zeta funciton associated to the Euler characteristic of X are identified using work of Bunke and Olbrich.
Scattering poles for asymptotically hyperbolic manifolds

"... Abstract.

Abstract. For a class of manifolds X that includes quotients of real hyperbolic (n + 1)dimensional space by a convex cocompact discrete group, we show that the resonances of the meromorphically continued resolvent kernel for the Laplacian on X coincide, with multiplicities, with the poles of the meromorphically continued scattering operator for X. In order to carry out the proof, we use Shmuel Agmon’s perturbation theory of resonances to show that both resolvent resonances and scattering poles are simple for generic potential perturbations. 1.

We construct a determinant of the Laplacian for infinitearea surfaces which are hyperbolic near infinity and without cusps. In the case of a convex cocompact hyperbolic metric, the determinant can be related to the Selberg zeta function and thus shown to be an entire function of order two with zeros at the eigenvalues and resonances of the Laplacian. In the hyperbolic near infinity case the determinant is analyzed through the zetaregularized relative determinant for a conformal metric perturbation. We establish that this relative determinant is a ratio of entire functions of order two with divisor corresponding to eigenvalues and resonances of the perturbed and unperturbed metrics. These results are applied to the problem of compactness in the smooth topology for the class of metrics with a given set of eigenvalues and resonances.

Abstract. For hyperbolic Riemann surfaces of finite geometry, we study Selberg’s zeta function and its relation to the relative scattering phase and the resonances of the Laplacian. As an application we show that the conjugacy class of a finitely generated, torsionfree, discrete subgroup of SL(2, R) is determined by its trace spectrum up to finitely many possibilities, thus generalizing results of McKean [19] and Müller [22] to groups which are not necessarily cofinite. 1.

. We exhibit pairs of infinitevolume, hyperbolic threemanifolds that have the same scattering poles and conformally equivalent boundaries, but which are not isometric. The examples are constructed using Schottky groups and the Sunada construction. In memory of Evsey Dyn'kin 1. Introduction The purpose of this paper is to explore the spectral geometry of the scattering operator by exhibiting examples of infinite volume hyperbolic threemanifolds that are `isoscattering' in a sense we will make precise, but have distinct geometries. To do so we will work with convex cocompact hyperbolic manifolds associated to Schottky groups of hyperbolic isometries. This class of manifolds, described in greater detail in what follows, may be thought of as interiors X of handlebodies X equipped with a metric that puts the boundary at metric infinity. The interior carries a hyperbolic structure, and the boundary, @ X , carries an induced conformal structure as a Riemann surface. Associated to the ...

.For convex cocompact hyperbolic manifolds of even dimension n +1,we deriveaPoissontype formula for scattering resonances whichmay be regarded as a version of Selberg's trace formula for these manifolds. Using techniques of Guillop'e and Zworski we easily obtain an O ; R n+1 \Delta lower bound for the counting function for scattering resonances together with other lower bounds for the counting function of resonances in strips. 1. Introduction In [12], Guillop'e and Zworski proveaPoisson summation formula for the scattering resonances of a hyperbolic surface X with finite geometry, i.e., X consisting of a compact manifoldwithboundary together with a finite number of cusps and funnels. This Poisson summation formula implies a polynomial lower bound on the counting function for scattering resonances and lower bounds for the counting function of scattering resonances in strips. Our purpose here is to generalize both the Poisson summation formula and the lower bounds on resonances to ...
