Algebraic intersection, lengths and Veech surfaces
Abstract: In this paper, we continue the study of intersections of closed curves on translation surfaces, initiated in by S. Cheboui, A. Kessi and D. Massart for a family of arithmetic Veech surfaces and the author, E. Lanneau and D. Massart for a family of non-arithmetic Veech surfaces. Namely, we investigate the question of maximizing the algebraic intersection between two curves of given lengths by studying the quantity KVol defined for any closed orientable surface by: $$ \mathrm{KVol}(X): = \mathrm{Vol}(X,g)\cdot \sup_{\alpha,\beta} \frac{\mathrm{Int} (\alpha,\beta)}{l_g (\alpha) l_g (\beta)},$$ where the supremum is taken over all pairs of closed curves on $X$. In this paper we focus on regular $n$-gons for even $n \geq 8$ as well as their Teichm\"uller disks.
