rational double points of algebraic surfaces are the Du Val singularities. Elliptic singularity (Kollár & Mori 1998, Theorem 5.22.) (Artin 1966) Artin...

the quotient of C2 by the action of a binary polyhedral group is a Du Val singularity. For point groups that reverse orientation, the situation is more...

using each discrete subgroup leads to an ADE-type singularity at the origin, termed a du Val singularity. The McKay correspondence can be extended to multiply...
