DESCRIPTION:Title: <a href="https://researchseminars.org/talk/algsjtu/3/">
 Surface skein algebras\, categorification and positivity</a>\nby Hoel Quef
 felec (Institut Montpelliérain Alexander Grothendieck) as part of SJTU al
 gebra seminar\n\n\nAbstract\nSkein algebra for surfaces appear in quantum 
 topology as natural generalizations of the Jones polynomial to thickened s
 urfaces. They enjoy deep connections with the theory of cluster algebras\,
  which partly motivated the conjecture by Fock-Goncharov-Thurston that the
 se algebras should admit a basis with positive structure constants.\nI wil
 l explain a proof of a version of such a conjecture based on the use of ca
 tegorification tools from quantum algebra.\n\nThis is based on joint work 
 with Kevin Walker and Paul Wedrich\n\n\nzoom id: 936 7477 0787\npasword: 5
