Milnor代数的变形

Deformation of Milnor Algebras

Zhenjian Wang

摘要:

研究了光滑齐次多项式的Milnor代数的变形,特别证明了:对于任何$d-1\leq k\leq (n+1)(d-2)$,任何以$n+1$为变量的光滑次数$d$齐次多项式,只要不是Patitiani-Thom型的,都是由其Jacobian理想的次数$k$齐次分量决定的.我们的结果推广了以前关于齐次多项式从其雅可比理想重构的结果。

英文摘要:

We investigate deformations of Milnor algebras of smooth homogeneous polynomials, and prove in particular that any smooth degree $d$ homogeneous polynomial in $n+1$ variables that is not of Sebastiani-Thom type is determined by the degree $k$ homogeneous component of its Jacobian ideal for any $d-1\leq k\leq (n+1)(d-2)$. Our results generalize the previous result on the reconstruction of a homogeneous polynomial from its Jacobian ideal.
