Abstract
Let V=C2⊗C2⊗C2 be the space of 2×2×2 hypermatrices, endowed with the natural group action of GL=GL2(C)×GL2(C)×GL2(C). The category of GL-equivariant coherent left D-modules on V is equivalent to the category of representations of a quiver with relations. In this article, we give a construction of each simple object and study their GL-equivariant structure. Using this information, we go on to explicitly describe the corresponding quiver with relations. As an application, we compute all iterations of local cohomology with support in the orbit closures of V.
