关于幂稳定理想

On Power Stable Ideals

Pramod K. Sharma

摘要:

定义了整环$ R $上多项式环$ R[X]$中幂稳定理想的概念。证明了$ R[X]$中的极大理想$χ$ $ M $是幂稳定的当且仅当对于素理想$ t\geq 1 $,$ P^t $是$ P$ -准素的.证明了对于Hilbert整环$R$,$R[X]$中的任意根理想是有限交G-理想,则它是幂稳定的.进一步证明了如果$ R $是1维Noether整环,则$ R[X] $中的任意根理想都是幂稳定的.最后,证明了如果$ R[X]$中的每个理想都是幂稳定的,则$ R $是一个域.

英文摘要:

We define the notion of a power stable ideal in a polynomial ring $ R[X]$ over an integral domain $ R $. It is proved that a maximal ideal $χ$ $ M $ in $ R[X]$ is power stable if and only if $ P^t $ is $ P$- primary for all $ t\geq 1 $ for the prime ideal $ P = M \cap R $. Using this we prove that for a Hilbert domain $R$ any radical ideal in $R[X]$ which is a finite intersection G-ideals is power stable. Further, we prove that if $ R $ is a Noetherian integral domain of dimension 1 then any radical ideal in $ R[X] $ is power stable. Finally, it is proved that if every ideal in $ R[X]$ is power stable then $ R $ is a field.
