SUMMARY:Christopher-Lloyd SIMON (IRMAR Rennes): Transcendance of simple geo
 desics in arithmetic surfaces
DESCRIPTION:Christopher-Lloyd SIMON: \nSubtitle : Dynamics of modular group
 s and diophantine approximation\n\nAbstract : We will introduce the dioph
 antine approximation of Markov numbers through the lens of hyperbolic geom
 etry and mapping class group dynamics. After revisiting the work and expos
 itions of Harvey Cohn\, Andrew Haas and Caroline Series from a topological
  viewpoint\, we will combine this picture with the dynamics of mapping cl
 ass groups on character varieties and the arithmetic of modular forms\, to
  propose new results and conjectures.
