| Beschreibung | Since several years it is known that certain discretizations for the geodesic flow on hyperbolic surfaces of \emph{finite area} allow to provide a dynamical characterizations of Maass cusp forms and a transfer-operator-based construction of their period functions. An important ingredient for these results is the characterization of Laplace eigenfunctions in parabolic cohomology by Bruggeman--Lewis--Zagier. We discuss an extension of these results to Hecke triangle surfaces of \emph{infinite area} and Laplace eigenfunctions that are more general than Maass cusp forms. This is joint work with R. Bruggeman. |
