DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/35/">D
 ifferential equations and deformations of supersymmetric QFT</a>\nby Andy 
 Neitzke (Yale University) as part of NHETC Seminar\n\n\nAbstract\nThere is
  a connection between N=2 supersymmetric field theory in four dimensions a
 nd the theory of linear differential and difference equations with meromor
 phic coefficients. This connection is surprisingly rich\, and has been stu
 died by many different authors from different perspectives. One way of und
 erstanding it is as an instance of the general phenomenon that turning on 
 Omega-background naturally quantizes algebraic structures in the operator 
 algebras of supersymmetric QFT. I will recall this connection and describe
  some of its uses\, along with some recent and ongoing extensions of the s
 tory.\n
