Title: DE singularities, Quot schemes and generating functions

Abstract: Starting with an ADE singularity C^2/Gamma for Gamma a finite 
subgroup of SL(2,C), one can build various moduli spaces of geometric 
and representation-theoretic interest as Nakajima quiver varieties. 
These spaces depend in particular on a stability parameter; quiver 
varieties at both generic and non-generic stability are of geometric 
interest. Generating functions of Euler characteristics at different 
points in stability space are controlled by specialisation formulae of 
characters of Lie algebra representations. We will explain some of these 
connections, focusing in particular on the abelian case. Based on joint 
papers and projects with Craw, Gammelgaard, Gyenge, and Nemethi.
