Spectral theory for transfer operators on compact quotients of Euclidean buildings

Joachim Hilgert, Daniel Kahl, Tobias Weich

In this paper we generalize the geodesic flow on (finite) homogeneous graphs to a multiparameter flow on compact quotients of Euclidean buildings. Then we study the joint spectra o…

Resonances on geometrically finite graphs

Christian Arends, Carsten Peterson, Tobias Weich

In analogy with the spectral theory of geometrically finite hyperbolic manifolds, we initiate the study of resonances on geometrically finite (q+1)-regular graphs of groups. We pro…

The spectrum of Anosov representations

Yannick Guedes Bonthonneau, Thibault Lefeuvre, Tobias Weich

Given a -Anosov representation into a noncompact semisimple real algebraic group , where is a parabolic subgroup, we construct a natural resonance spectrum for the cl…

Polyhedral bounds on the joint spectrum and temperedness of locally symmetric spaces

Christopher Lutsko, Tobias Weich, Lasse L. Wolf

Given a real semisimple connected Lie group and a discrete subgroup we prove a precise connection between growth rates of the group , polyhedral bounds on the joint s…

Invariant Ruelle Distributions on Convex-Cocompact Hyperbolic Surfaces -- A Numerical Algorithm via Weighted Zeta Functions

Philipp Schütte, Tobias Weich

We present a numerical algorithm for the computation of invariant Ruelle distributions on convex co-compact hyperbolic surfaces. This is achieved by exploiting the connection betwe…

Spectral correspondences for finite graphs without dead ends

Kai-Uwe Bux, Joachim Hilgert, Tobias Weich

We compare the spectral properties of two kinds of linear operators characterizing the (classical) geodesic flow and its quantization on connected locally finite graphs without dea…
