Abstract

In this paper we investigate the systolic landscape of translation surfaces for fixed genus and fixed angles of their cone points. We furthermore study how the systoles of a translation surface relate to the systoles of its graph of saddle connections. This allows us to develop an algorithm to compute the systolic ratio of origamis in the stratum H(1,1)\mathcal{H}(1,1). We compute the maximal systolic ratio of all origamis in H(1,1)\mathcal{H}(1,1) with up to 67 squares. These computations support a conjecture of Judge and Parlier about the maximal systolic ratio in H(1,1)\mathcal{H}(1,1).
