SUMMARY:S-duality and mirror symmetry in Chern-Simons theory - Dimofte\, T
  (Princeton)

DESCRIPTION:I will present joint work with S. Gukov on S-duality in three-
 dimensional Chern-Simons theories. Upon analytic continuation\, the Chern-
 Simons "level" k can be taken to be an arbitrary complex number. Then\, bo
 th Chern-Simons wavefunctions and certain operators that annihilate them a
 cquire a certain symmetry under the inversion of k (S-duality). In terms o
 f the operators\, this can be understood in terms of mirror symmetry actin
 g on branes in a hyperkahler space (a Hitchin moduli space).\n
