“Sheaves on root stacks and Nakajima quiver varieties”

In the present talk I describe a (conjectural) relation between moduli spaces of (framed) sheaves on some two-dimensional root toric stacks and Nakajima quiver varieties of type the affine Dynkin diagram Aˆn. If time permits, I will discuss an application of this relation to representation theory of Kac-Moody algebras (and vertex algebras).
