DESCRIPTION:Speaker: Zhiwei Yun\nhosted by Tamas Hausel\nAbstract: The glob
 al nilpotent cone is the zero fiber of the Hitchin map in the moduli space
  of Higgs bundles over an algebraic curve. It is a conic Lagrangian in the
  ambient symplectic moduli space\, and it plays an important role in the g
 eometric Langlands program. In this talk we define a version of the global
  nilpotent cone for a family of curves. It will be a closed conic Lagrangi
 an in the cotangent bundle of the total space of the family of Bun_G's for
  the family of curves. Implicitly it encodes a "connection" among the cate
 gory of sheaves on Bun_G as the curve varies. I will mention the motivatio
 n of the construction from Betti geometric Langlands. This is joint work w
 ith David Nadler.Notes:  https://seafile.ist.ac.at/f/4a298acb2afe4d648e89
