DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/1/">Fa
 milies of Hitchin systems and N=2 theories</a>\nby Aswin Balasubramanian (
 Rutgers) as part of NHETC Seminar\n\n\nAbstract\nOver the last few years\,
  the connection between 4d N=2 theories and Hitchin systems has led to a r
 obust exchange of ideas between physics and mathematics. In my talk\, I wi
 ll explain how to extend this dictionary to one between 4d N=2 physics and
  the SL_N Hitchin system on a nodal UV Curve. I will then use this diction
 ary to clarify certain questions concerning Coulomb branches of the corres
 ponding Class S theories at various boundaries of the space of marginal pa
 rameters. In mathematical terms\, I will describe tame SL_N Hitchin system
 s as a flat family of integrable systems over \\bar{M}\, the Deligne-Mumfo
 rd moduli space of the UV Curve. This is based on upcoming work with J. Di
 stler and R. Donagi.\n
