摘要

我们证明了类型为（d，…，d）（d，\dots，d）的Artinian完全交的关联形式，或者等价地，Macaulay逆系统是多稳态的。作为一个应用，我们得到了齐次超曲面奇点的Mather-Yau定理的一个不变理论变体。

Stability of associated forms

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.
