SUMMARY:Pen Shang (Tsinghua University): Monoidal categorification of skein
  algebras
DESCRIPTION:Pen Shang: Skein algebras of surfaces are basic objects of stud
 y in quantum topology. They provide natural quantisation of character vari
 eties. In this talk\, we explain an isomorphism between the Kauffman brack
 et skein algebra of a genus zero surface with boundary and a quantized K-t
 heoretic Coulomb branch. As a consequence\, we see that our skein algebra 
 arises as the Grothendieck ring of the bounded derived category of equivar
 iant coherent sheaves on the Braverman–Finkelberg–Nakajima variety of 
 triples. We thus obtain a monoidal categorification of the skein algebra\,
  partially answering a question posed by D. Thurston. This is based on joi
 nt work with Dylan Allegretti and Hyun Kyu Kim.
