Stability of associated forms

Algebraic Geometry 2018-03-21 v5 Commutative Algebra

Abstract

We show that the associated form, or equivalently a Macaulay inverse system, of an Artinian complete intersection of type (d,,d)(d,\dots, d) is polystable. As an application, we obtain an invariant-theoretic variant of the Mather-Yau theorem for homogeneous hypersurface singularities.
