DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDS/6/">Clos
 ed geodesics on reversible Finsler 2-spheres</a>\nby Marco Mazzucchelli (E
 NS de Lyon) as part of Geometry and Dynamics seminar\n\n\nAbstract\nIn thi
 s talk\, I will show that two celebrated theorems on closed \ngeodesics of
  Riemannian 2-spheres still hold for the larger class \nof reversible Fins
 ler 2-spheres: Lusternik-Schnirelmann's theorem \nasserting the existence 
 of three simple closed geodesics\, and \nBangert-Franks-Hingston's theorem
  asserting the existence of \ninfinitely many closed geodesics. I will ske
 tch the proofs of \nthese statements\, employing in particular the Finsler
  generalization \nof Grayson's curve shortening flow developed by Angenent
 -Oaks. \nThis is joint work with Guido De Philippis\, Michele Marini\, and
  \nStefan Suhr.\n
