DESCRIPTION:Title: The systole of hyperbolic surfaces\n\nAbstract: The syst
 ole of a Riemannian manifold is defined as the infimal length of its close
 d geodesics that are not contractible and was studied by Berger and Gromov
  in the 70's and 80's. In this talk\, I will survey recent results on the 
 systole of closed hyperbolic surfaces. In particular\, I will explain how 
 to construct a surface out of polygons glued along a graph in a way that w
 e can determine its systole. Variants of this construction yield numerous 
 local maxima for the systole\, critical points of lower index than expecte
 d\, and are used to prove that the dimension of a certain set defined by T
 hurston is larger than hoped.\n\nUQAM\, PK-5115\, 201 Av. du Président-Ken
