DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HKUST-AG/80/
 ">The affine super Yangian of $\\mathfrak{gl}(1|1)$</a>\nby Yu Zhao (Beiji
 ng Institute of Technology) as part of Algebra and Geometry Seminar @ HKUS
 T\n\nLecture held in Room 4504 (Lifts 25/26).\n\nAbstract\nNakajima and Va
 fa-Witten noticed that the blow up formulae for the partition functions of
  Euler numbers on the instanton moduli space is the character of affine ve
 rtex algebra at level 1\, and asked the CFT explanation. Together with Jia
 ng and Li\, we answered this question. However\, our proof leaves more que
 stions: how do we explain the Donaldson polynomials and the Seiberg-Witten
  prepotential as correlation functions in Liouville theory? In this talk\,
  I will discuss the affine Yangian of $\\mathfrak{gl}(1|1)$\, and discuss 
 how to solve the above problems through a larger algebra action.\n
