DESCRIPTION:Speaker: Balazs Szendroi\nhosted by Tamas Hausel\nAbstract: Giv
 en a smooth algebraic surface S over the complex numbers\, the Hilbert sch
 eme of points of S is the starting point for many investigations\, leading
  in particular to generating functions with modular behaviour and Heisenbe
 rg algebra representations. I will explain aspects of a similar story for 
 surfaces with rational double points\, with links to algebraic combinatori
 cs and the representation theory of affine Lie algebras. I will in particu
 lar explain our 2015 conjecture concerning the generating function of thei
 r Euler characteristics\, and aspects of more recent work that lead to a v
 ery recent proof of the conjecture by Nakajima. Joint work with Gyenge and
  Nemethi\, respectively Craw\, Gammelgaard and Gyenge.
