The orientation-reversing minimal stretch factor problem in small genus

Pierre Dehornoy, Erwan Lanneau, Livio Liechti +1

We determine the minimal stretch factors among all orientation-reversing pseudo-Anosov mapping classes of the closed orientable surfaces of genus two, three and four.

Genus one Birkhoff sections for geodesic flows on orbifolds

Pierre Dehornoy

For $O$ a hyperbolic orientable 2-orbifold of genus $g$ with at most $2 g + 6$ conic points, we prove that the geodesic flow on the unitary tangent bundle$\mathrm{T}^1\mathc…
