一维赋值环作为光滑代数的极限

Valuation rings of dimension one as limits of smooth algebras

Dorin Popescu

AI总结:

本文证明在特定超越度条件下,特征p>0的一维赋值环可表示为光滑F_p-代数的滤过直接极限,并探讨了代数立即扩张的稠密性。

摘要:

如Zariski均匀化定理所述,我们证明在超越度的某些条件下,特征为$p>0$的一维赋值环$V$是光滑${\f F}_p$-代数的滤过直接极限。在温和条件下,若赋值环的代数立即扩张是光滑态射的滤过直接极限,则它们是稠密的。

英文摘要:

As in Zariski's Uniformization Theorem we show that a valuation ring $V$ of characteristic $p>0$ of dimension one is a filtered direct limit of smooth ${\bf F}_p$-algebras under some conditions of transcendence degree. Under mild conditions, the algebraic immediate extensions of valuation rings are dense if they are filtered direct limit of smooth morphisms.
