继 Mustaţă 和 Bitoun 的工作之后,我们最近提出了任意理想的 Bernstein-Sato 根的概念,这是 Bernstein-Sato 多项式的根的主要特征类似物。在这里,我们证明,对于单项式理想,Bernstein-Sato 多项式的根(超过 $mathbb{C}$)与 $p$ 足够大时理想的 mod-$p$ 约简的 Bernstein-Sato 根一致。我们将此视为 Bernstein-Sato 根的特征 $p$ 概念合理的证据。
Following work of Mustaţă and Bitoun we recently developed a notion of Bernstein-Sato roots for arbitrary ideals, which is a prime characteristic analogue for the roots of the Bernstein-Sato polynomial. Here we prove that for monomial ideals the roots of the Bernstein-Sato polynomial (over $mathbb{C}$) agree with the Bernstein-Sato roots of the mod-$p$ reductions of the ideal for $p$ large enough. We regard this as evidence that the characteristic-$p$ notion of Bernstein-Sato root is reasonable.
