We then use these interpretations to establish explicit isomorphisms between spaces of automorphic forms, cohomology spaces and spaces of eigenfunctions of transfer operators. These results show a deep relation between spectral entities of Hecke surfaces of infinite volume and the dynamics of their geodesic flows.", "revisions": [ { "version": "v1", "updated": "2019-09-25T12:18:23.000Z" } ], "analyses": { "subjects": [ "11F12", "11F67", "37C30", "11F72", "30F35", "37D40" ], "keywords": [ "hecke triangle groups", "automorphic forms", "transfer operators", "infinite covolume", "eigenfunctions" ], "note": { "typesetting": "TeX", "pages": 137, "language": "en", "license": "arXiv", "status": "editable" } } }
