DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UBC-AG/2/">T
 he skein algebra of the 4-punctured sphere from curve counting</a>\nby Pie
 rrick Bousseau (ETH Zürich) as part of UBC Vancouver Algebraic Geometry S
 eminar\n\n\nAbstract\nThe Kauffman bracket skein algebra is a quantization
  of the algebra of regular functions on the SL_2 character variety of a to
 pological surface. I will explain how to realize the skein algebra of the 
 4-punctured sphere as the output of a mirror symmetry construction based o
 n higher genus Gromov-Witten invariants of a log Calabi-Yau cubic surface.
  This leads to a proof of a previously conjectured positivity property of 
 the bracelets bases of the skein algebras of the 4-punctured sphere and of
  the 1-punctured torus.\n
