Abstract

Coble hypersurfaces Degeneracy loci subvarieties of Grassmannians Moduli spaces of abelian varieties Kummer varieties Graded Lie algebras Macdonald representations Heisenberg groups
We show that the Coble hypersurfaces, uniquely characterized by the remarkable property that their singular loci are an abelian surface and a Kummer threefold, respectively, belong to a family of hypersurfaces exhibiting similar behavior, but defined in various types of homogeneous spaces. With the help of Jordan-Vinberg theory, we show how these hypersurfaces can be parametrized by Göpel type varieties inside projectivized representations of complex reflection groups.
