25 p, 464.2 KB The minimal length product over homology bases of manifolds / Balacheff, Florent Nicolas (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Karam, Steve (Lebanese University) ; Parlier, Hugo (University of Luxembourg. Department of Mathematics)
Minkowski's second theorem can be stated as an inequality for n-dimensional flat Finsler tori relating the volume and the minimal product of the lengths of closed geodesics which form a homology basis. [...]

22 p, 510.2 KB Bers' constants for punctured spheres and hyperelliptic surfaces / Balacheff, Florent Nicolas (Université de Lille. Laboratoire Paul Painlevé) ; Parlier, Hugo (University of Fribourg. Department of Mathematics)
The main goal of this paper is to present a proof of Buser's conjecture about Bers' constants for spheres with cusps (or marked points) and for hyperelliptic surfaces. More specifically, our main result states that any hyperbolic sphere with n cusps has a pants decomposition with all of its geodesics of length bounded by 30√2π(n-2). [...]

In this note, we observe that the maximum value achieved by the systole function over all complete finite area hyperbolic surfaces of a given signature is greater than a function that grows logarithmically in terms of the ratio . [...]

Laboratoire Paul Painlevé) ; Parlier, Hugo (University of Fribourg. Department of Mathematics) ; Sabourau, Stéphane (Université Paris-Est Créteil. Laboratoire d'Analyse et de Mathématiques, Appliquées)
Given a Riemannian surface, we consider a naturally embedded graph which captures part of the topology and geometry of the surface. By studying this graph, we obtain results in three different directions. [...]

14 p, 380.7 KB Systoles and diameters of hyperbolic surfaces / Balacheff, Florent Nicolas (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Despré, Vincent (Université de Lorraine. Polytech Nancy) ; Parlier, Hugo (University of Luxembourg. Department of Mathematics)
In this article we explore the relationship between the systole and the diameter of closed hyperbolic orientable surfaces. We show that they satisfy a certain inequality, which can be used to deduce that their ratio has a (genus-dependent) upper bound.

19 p, 202.1 KB Convexity of strata in diagonal pants graphs of surfaces / Aramayona, Javier ; Lecuire, Cyril ; Parlier, H. ; Shackleton, K. J.
We prove a number of convexity results for strata of the diagonal pants graph of a surface, in analogy with the extrinsic geometric properties of strata in the Weil-Petersson completion. As a consequence, we exhibit convex flat subgraphs of every possible rank inside the diagonal pants graph.
