DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGPhy/1/">Sk
 ein modules of closed 3-manifolds</a>\nby Renaud Detcherry (Universite de 
 Bourgogne) as part of Algebra\, Geometry and Physics seminar (MPIM Bonn/HU
  Berlin)\n\nLecture held in Meeting ID: 836 1355 9205 Password: 120672.\n\
 nAbstract\nThe Kauffman bracket skein module of a 3-manifold M is a Q(A)-v
 ector space\, describing the combinatorics of links in M up to some local 
 relations. Computing the skein module of a given 3-manifold has long been 
 a hard question and besides a few examples\, no general algorithm is known
 . However a recent conjecture of Witten\, now proven non constructively by
  Gunningham\, Jordan and Safronov\, states that the skein module of a clos
 ed 3-manifold is finite dimensional. After discussing the motivations behi
 nd the conjecture and some open questions\, we will present some joint wor
 k with Maxime Wolff\, describing explicitly the skein module of the produc
 t of a surface and a circle.\n
