DESCRIPTION:Langlands duality originated in number theory\, was translated
  into algebraic geometry of projective curves by Beilinson\, Drinfeld\, Ar
 inkin\, Gaitsgory and many others\; and subsequently re-interpreted in qua
 ntum field theory by Kapustin and Witten.\n\nIn this talk I'll explain a n
 ovel conjectural appearance of Langlands duality in the quantum topology o
 f 3-manifolds via so-called skein modules\, which are deformation quantiza
 tions of character varieties of 3-manifolds.  One pleasant feature in this
  context is that Langlands duality is very elementary: it is the assertion
  that two integers -- computed from M using a group G and its Langlands du
 al -- are equal.  The conjecture and the evidence I'll present is joint wo
 rk with various of Ben-Zvi\, Gunningham\, Safronov\, Vazirani and Yang.
