关于符号Rees代数的素理想结构

On the prime ideal structure of symbolic Rees algebras

S. Bouchiba, S. Kabbaj

摘要:

本文研究了Noether整环上符号Rees代数的素谱和维数论。我们首先建立一些一般性的结果的素理想结构的仿射域,实际上出现,在诺特的上下文中,作为域之间的域$A$和$A[a^{-1}]$。然后,我们仔细研究的特殊情况下,符号里斯代数(产生了第一个反例的Zagliki希尔伯特问题)。其中一个结果表明,如果$A$是Noether整环,$p$是$A$的极大理想,则$p$的Rees代数继承了作为稳定强S-整环的Noether类行为.我们还研究了与素理想$p$的符号Rees代数相关的分次环,使得$A_{p}$是秩为1的DVR,并与Hochster关于素理想的普通幂和符号幂重合的结果相关的应用密切。

英文摘要:

This paper contributes to the study of the prime spectrum and dimension theory of symbolic Rees algebra over Noetherian domains. We first establish some general results on the prime ideal structure of subalgebras of affine domains, which actually arise, in the Noetherian context, as domains between a domain $A$ and $A[a^{-1}]$. We then examine closely the special context of symbolic Rees algebras (which yielded the first counter-example to the Zariski-Hilbert problem). One of the results states that if $A$ is a Noetherian domain and $p$ a maximal ideal of $A$, then the Rees algebra of $p$ inherits the Noetherian-like behavior of being a stably strong S-domain. We also investigate graded rings associated with symbolic Rees algebras of prime ideals $p$ such that $A_{p}$ is a rank-one DVR and close with an application related to Hochster's result on the coincidence of the ordinary and symbolic powers of a prime ideal.
