关于齐次多项式的Brieskorn模的挠率
On the torsion of Brieskorn modules of homogeneous polynomials
摘要:
设$f\in \mathbb{C}[X_1,..., X_n]$是一个齐次多项式,B(f)是相应的Brieskorn模.我们描述了n=2时Brieskorn模B(f)的扭转,并证明任何扭元都有1阶。对于n>2,我们找到了挠序严格大于1的一些例子。
英文摘要:
Let $f\in \mathbb{C}[X_1,..., X_n]$ be a homogeneous polynomial and B(f) be the corresponding Brieskorn module. We describe the torsion of the Brieskorn module B(f) for n=2 and show that any torsion element has order 1. For n>2, we find some examples in which the torsion order is strictly greater than 1.
