Kirillov [16] has described a McKay correspondence for finite subgroups ofthat associates to each “height” function an affine Dynkin quiver together with a derived equivalence between equivariant sheaves onand representations of this quiver. The equivalences for different height functions are then related by reflection functors for quiver representations. The main goal of this article is to develop an analogous story for the cotangent bundle of. We show that each height function gives rise to a derived equivalence between equivariant sheaves on the cotangent bundleand modules over the preprojective algebra of an affine Dynkin quiver. These different equivalences are related by spherical twists, which take the place of the reflection functors for.
