Although translation surfaces have been intensively studied since the 1980’s, there are still many natural questions wildly open.

One of these questions is: what is the maximal systolic ratio in a stratum, i.e. what is the maximal length of a shortest simple closed geodesic on a translation surface of area 1 in a fixed stratum? We study this question of translation surfaces of genus 2 with two singularities.

This is joint work with Colombus, Herrlich, Mützel.

dashed line is a systole (, fig.4, page 23)
