Translation surfaces with large systoles

Peter Buser, Eran Makover, Bjoern Muetzel

Abstract

In this paper we continue to investigate the systolic landscape of translation surfaces started in [CHMW]. We show that there is an infinite sequence of surfaces $(S_{g_k})_k$ of genus $g_k$, where $g_k \to \infty$ with large systoles. On the other hand we show that for hyperelliptic surfaces we can find a suitable homology basis, where a large number of loops that induce the basis are short.

Key Result

Theorem 1.1

Let $S_{max}$ be a maximal translation surface of genus $g \geq 1$. Then every simple closed geodesic that does not run through a cone point is intersected by a systole of $S_{max}$.

  • Figure 2: Dashed and full lines are identified in each of the two rectangles to obtain the two tori $P_1$ and $P_2$. These are glued together along the slit to obtain the surface $X$.
