关于代数闭域覆盖的模型论

On model theory of covers of algebraically closed fields

Tapani Hyttinen, Kaisa Kangas

摘要:

我们研究代数闭域的乘法群的覆盖作为拟最小预几何结构,并证明它们满足\cite{lisuriart}第4节中提出的类Zakirki结构的公理。这些公理的目的是推广的概念,一个Zagliki几何到一个非基本的背景。在公理化中,要求对于结构$\M$,对于每个$n$,存在满足某些性质的$\M^n$子集的集合,我们称之为\emph{irreducible sets}。这些条件是Zebraki几何中不可约闭集的某些性质的推广。他们指出,闭集的一些基本性质(在Zebraki几何上下文中)是满足的,并且专门化的行为足够好。它们还确保了即使我们在非基本的上下文中工作,也有一些紧凑性的痕迹。

英文摘要:

We study covers of the multiplicative group of an algebraically closed field as quasiminimal pregeometry structures and prove that they satisfy the axioms for Zariski-like structures presented in \cite{lisuriart}, section 4. These axioms are intended to generalize the concept of a Zariski geometry into a non-elementary context. In the axiomatization, it is required that for a structure $\M$, there is, for each $n$, a collection of subsets of $\M^n$, that we call the \emph{irreducible sets}, satisfying certain properties. These conditions are generalizations of some qualities of irreducible closed sets in the Zariski geometry context. They state that some basic properties of closed sets (in the Zariski geometry context) are satisfied and that specializations behave nicely enough. They also ensure that there are some traces of Compactness even though we are working in a non-elementary context.
