DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UMassRep/13/
 ">Integrable systems from Calabi-Yau categories</a>\nby Nick Rozenblyum (U
 niversity of Chicago) as part of UMass Amherst Representation theory semin
 ar\n\n\nAbstract\nI will describe a general categorical approach to constr
 ucting Hamiltonian actions on moduli spaces.\nIn particular cases\, this s
 pecializes to give a "universal" Hitchin integrable system as well as\nthe
  Calogero-Moser system.  Moreover\, I will describe a generalization to hi
 gher dimensions of a classical\nresult of Goldman which says that the Gold
 man Lie algebra of free loops on a surface acts by Hamiltonian\nvector fie
 lds on the character variety of the surface.  A key input is a description
  of deformations of\nCalabi-Yau structures\, which is of independent inter
 est.  This is joint work with Chris Brav.\n
