摘要:
我们证明了有限投射模的下降结果,受完美几何中一个问题的启发。给定一个交换环A,我们提出一个问题:如何将带有系数A的Novikov环上的有限投射模下降到A上的有限投射模。本文的主要定理是所有此类下降数据都是有效的。作为应用,我们证明对于每一个完美F_p-代数A,Spd A上的向量包总是可以下降到Spec A上的向量包。
英文摘要:
We prove a descent result for finite projective modules, motivated by a question in perfectoid geometry. Given a commutative ring $A$, we formulate a descent problem for descending a finite projective module over the Novikov ring with coefficients in $A$ to a finite projective module over $A$. The main theorem of this paper is that all such descent data are effective. As an application, we prove for every perfect $\mathbb{F}_p$-algebra $A$, a vector bundle on $\operatorname{Spd} A$ always descends to a vector bundle on $\operatorname{Spec} A$.
