Let G ⊆ GL(n) be a finite group without pseudo-reflections. We present an algorithm to compute and verify a candidate for the Cox ring of a resolution X → C n /G, which is based just on the geometry of the singularity C n /G, without further knowledge of its resolutions. As an application, we determine the Cox rings of resolutions X → C 3 /G for all G ⊆ GL… (More)
