A GKM Description of the Equivariant Coinvariant Ring of a Pseudo   Reflection Group
  We identify the equivariant coinvariant ring of a pseudo-reflection group with its image under the localization map. We then show that this image can be realized as the equivariant cohomology of a sort linear hypergraph, analogous to a GKM 1-skeleton.
