Genus one Birkhoff sections for geodesic flows
arXiv:1208.6405 · doi:10.1017/etds.2014.14
Abstract
We prove that the geodesic flow on the unit tangent bundle to every hyperbolic 2-orbifold that is a sphere with 3 or 4 singular points admits explicit genus one Birkhoff sections, and we determine the associated first return maps.
