DESCRIPTION:Speaker: Hiraku Nakajima\nhosted by Tamas Hausel\nAbstract: The
  S-dual (G∨M∨) of the pair (GM) of a smooth affine algebraic sympl
 ectic manifold M with hamiltonian action of a complex reductive group G
  was introduced implicitly in [arXiv:1706.02112 (https://arxiv.org/abs/17
 06.02112)] and explicitly in [arXiv:1807.09038 (https://arxiv.org/abs/1807
 .09038)] under the cotangent type assumption. The definition was a modific
 ation of the definition of Coulomb branches of gauge theories in [arXiv:16
 01.03586 (https://arxiv.org/abs/1601.03586)]. It was motivated by the S-du
 ality of boundary conditions of 4-dimensional N=4 super Yang-Mills theor
 y\, studied by Gaiotto and Witten [arXiv:0807.3720 (https://arxiv.org/abs/
 0807.3720)]. It is also relevant to the relative Langlands duality propose
 d by Ben-Zvi\, Sakellaridis and Venkatesh. In this article\, we review the
  definition and properties of S-dual.
