DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/125/">D
 ynamics of torus homeomorphisms and the fine curve graph</a>\nby Sebastian
  Hensel (LMU Munich) as part of Geometry and topology online\n\nLecture he
 ld in Room B3.02 in the Zeeman Building\, University of Warwick.\n\nAbstra
 ct\nThe fine curve graph is a Gromov hyperbolic graph on which the homeomo
 rphism group of a surface acts.  We relate the surface dynamics of a torus
  homeomorphism to its action on the fine curve graph.  In particular we sh
 ow that the shape of a “big" rotation set is determined by the fixed poi
 nts on the Gromov boundary of the graph.  A key ingredient is a metric ver
 sion of the WPD property for the homeomorphism group of the torus.\n\nThis
  is joint work with Frédéric Le Roux.\n
