Algebraic intersection on Veech surfaces
- Julien Boulanger (Institut Fourier, Grenoble)
Abstract
In this talk we will investigate the maximal possible intersection of closed curves of a given length on a surface, and we will specifically focus on the case of translation surfaces. One way to approach this question is to consider the so-called (algebraic) interaction strength (here denoted KVol). After having introduced a few notions related to KVol as well as translation surfaces, we will give a method to compute KVol on SL_2(R)-orbits of Bouw-Möller surfaces with a single singularity, which are instances of particularly symmetric translation surfaces (their Veech group are triangle groups).
