Greenberg定理在一般赋值环上的推广

An extension of Greenberg's theorem to general valuation rings

Laurent Moret-Bailly

摘要:

利用Becker,Denef,Lipshitz和van den Dries的超积方法,将Greenberg强逼近定理推广到具有任意值群的赋值环上的有限表示格式.作为应用,我们证明了值域上簇的真态射的一个闭象定理(在有理点上的强拓扑中)。

英文摘要:

We extend Greenberg's strong approximation theorem to schemes of finite presentation over valuation rings with arbitrary value group, using the ultraproduct method of Becker, Denef, Lipshitz and van den Dries. As an application, we prove a closed image theorem (in the strong topology on rational points) for proper morphisms of varieties over valued fields.
