Letbe a complex classical simple Lie algebra and letObe a nilpotent orbit of. The fundamental groupis finite. Take the universal covering. Thenextends to a finite cover. By using the Kirillov–Kostant formonO, the normal affine varietyXbecomes a conical symplectic variety. In this article we give an explicit construction of aQ-factorial terminalization ofX.
