The McKay correspondence in type $D_4$ via VGIT

Algebraic Geometry 2024-02-09 v1

Abstract

We present an explicit GIT construction which produces both the minimal resolution of the type D4D_4 surface singularity, and also the orbifold resolution. Our construction is based on a Tannakian approach which is in principle applicable to arbitrary quotient singularities.
