We show that if the geodesic billiard system is hyperbolic on its trapped set and the latter is compact and non-grazing, the techniques for open hyperbolic systems developed by Dyatlov and Guillarmou (Ann Henri Poincaré 17(11):3089–3146, 2016) can be applied to a smooth model for the discontinuous flow defined by the non-grazing billiard trajectories. This allows us to obtain a meromorphic resolvent for the generator of the billiard flow. As an application we prove a meromorphic continuation of weighted zeta functions together with explicit residue formulae. In particular, our results apply to scattering by convex obstacles in the Euclidean plane.</jats:p>","lang":"eng"}],"title":"Resonances and Weighted Zeta Functions for Obstacle Scattering via Smooth Models","date_updated":"2024-04-11T12:37:34Z","page":"1607-1656","language":[{"iso":"eng"}],"intvolume":"        25","issue":"2","department":[{"_id":"548"}],"citation":{"apa":"Delarue, B., Schütte, P., &#38; Weich, T.
