Bernhard Albach
We prove that for any reversible Finsler metric on S2, the number of prime closed geodesics grows quadratically with respect to length. The main tools are an improvement on Franks'…

Surfaces of section for Seifert fibrations
Bernhard Albach, Hansjörg Geiges
We classify global surfaces of section for flows on 3-manifolds defining Seifert fibrations. We discuss branched coverings -- one way or the other -- between surfaces of section fo…
