具有自同构的微分闭域的Zilber二分法
Zilber's Dichotomy for Differentially Closed Fields with an Automorphism
摘要:
特征零点的差分微分场理论有一个用$\it DCFA$表示的伴随模型。以前我们证明了$\it DCFA$的Zilber二分法的一个弱版本。在本文中,我们使用弧空间技术开发的Moosa,Pillay和Scanlon,以抑制额外的假设需要之前,并证明了完整的Zilber的二分法$\it DCFA$,我们还说明这些技术如何推广到偏微分场的自同构。
英文摘要:
The theory of difference-differential fields of characteristic zero has a model-companion denoted by $\it DCFA$. Previously we proved a weak version of Zilber's dichotomy for $\it DCFA$. In this paper we use arc spaces techniques as developed by Moosa, Pillay and Scanlon to suppress the extra hypothesis needed before and prove the full Zilber's dichotomy for $\it DCFA$, we also state how these techniques generalise to partial differential fields with an automorphism.
