特化态射

Specialization morphisms

Ildar Gaisin, John Welliaveetil

摘要:

我们定义了从局部诺特解析进空间到一个方案的特化态射的概念。这捕获了与形式概形相关联的(经典)专门化态射。有一个表现良好的紧化理论,它证明了经典的专门化态射是\emph{proper}在这个设置。作为应用,我们在很大程度上证明了附近圈函子以较低的尖叫交换。

英文摘要:

We define the notion of a specialization morphism from a locally noetherian analytic adic space to a scheme. This captures the (classical) specialization morphism associated to a formal scheme. There is a well behaved theory of compactifications and it turns out that the classical specialization morphism is \emph{proper} in this setup. As an application, we show that the nearby cycles functor commutes with lower shriek in great generality.
