DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geometry/22/
 ">On the relations between the universal Teichmuller space and Anti de Sit
 ter geometry</a>\nby Louis Merlin (Aachen University) as part of Pangolin 
 seminar\n\n\nAbstract\nAnti de Sitter (AdS) space is the Lorentzian cousin
  of the hyperbolic 3-space: it is a symmetric space with constant curvatur
 e -1. In this talk\, we will consider surface group representations in the
  isometry group of AdS space\, called quasi-Fuchsian representations. Ther
 e is 2 classical objects associated to those representations and one of th
 e goal is to understand their interplay: the limit set which is a quasi-ci
 rcle in the boundary at infinity of AdS space and a convex set inside AdS 
 which is preserved by the group action and bounded by two pleated surfaces
 . I will conclude the talk by a report on a work in common with Jean-marc 
 Schlenker where we extend the "Teichmüller" situation to the "universal T
 eichmüller".\n
