A counterexample to Guillemin's Zollfrei conjecture Link: https://doi.org/10.1142/S1793525313500143 Autor/in: Suhr, Stefan Erscheinungsjahr: 2013 Medientyp: Text Schlagworte: Lorentzian manifolds closed geodesics Beschreibung: We construct Zollfrei Lorentzian metrics on every non-trivial orientable circle bundle over an orientable closed surface. Further we prove a weaker version of Guillemin's conjecture assuming global hyperbolicity of the universal cover.
