Resonance Chains for Hyperbolic Surfaces with Large Funnels via Dynamical Zeta Functions

Henry Talbott

In this talk, I will quantitatively relate the resonance sets of certain hyperbolic surfaces to the resonance sets of certain metric graphs via the spine graph construction. Resonance sets of metric graphs are known to contain structures known as ‘resonance chains’, and so as a corollary I will show the existence of approximate resonance chains in resonance sets of these surfaces as specific geometric parameters become large. In the language of zeta functions, these results can be restated in terms of the Selberg zeta functions of these surfaces degenerating to polynomials under an asymptotic limit.
