On Gorenstein Surfaces Dominated by P2
Abstract
In this paper we prove that a normal Gorenstein surface dominated by the projective plane P2 is isomorphic to a quotient P2/G, where G is a finite group of automorphisms of P2 (except possibly for one surface V8'). We can completely classify all such quotients. Some natural conjectures when the surface is not Gorenstein are also stated.
