设R是域上本质有限型的环,I⊆R是一个理想,本文证明符号幂I⁽ⁿ⁾的最小生成元个数以n的多项式为上界。此外,若R是整环,且ℐ={Iₙ}ₙ≥₀是ℝ-除子滤过,则理想Iₙ的最小生成元个数同样以n的多项式为上界。
英文摘要
Let $R$ be a ring that is essentially of finite type over a field and $I\subseteq R$ be an ideal. In this article it is shown that the minimal number of generators of the symbolic powers $I^{(n)}$ is bounded above by a polynomial in $n$. Furthermore, if $R$ is assumed to be a domain and $\mathcal I=\{I_n\}_{n\ge 0}$ is an $\mathbb{R}$-divisorial filtration, then the minimal number of generators of the ideals $I_n$ is again bounded above by a polynomial in $n$.
