Abstract: We study Cox rings of minimal resolutions of quotients of the plane by an action of a finite subgroup of GL(2,C). We will show two methods of describing these rings. The first one is to give the equation for the spectrum, which is a hypersurface in an affine space. The second is to give a set of generators of the Cox ring in a simpler ring associated with the investigated singularity.
