算术几何中的权

Weights in arithmetic geometry

Uwe Jannsen

摘要:

代数簇上同调的权概念是由A。Grothendieck和P. Deligne。它与动机的概念有着深刻的联系,并首先出现在作为(可能是混合的)霍奇结构的权重的奇异上同调和作为Frobenius特征值的权重的etale上同调上。但权也出现在代数基本群和p进霍奇理论中,它们只有在应用方丹的比较函子后才能看到。在排练了各种版本的权重之后,我们解释了权重的一些最近的应用,例如,Hasse原理和动机上同调的计算,并讨论了一些悬而未决的问题。

英文摘要:

The concept of weights on the cohomology of algebraic varieties was initiated by fundamental ideas and work of A. Grothendieck and P. Deligne. It is deeply connected with the concept of motives and appeared first on the singular cohomology as the weights of (possibly mixed) Hodge structures and on the etale cohomology as the weights of eigenvalues of Frobenius. But weights also appear on algebraic fundamental groups and in p-adic Hodge theory, where they become only visible after applying the comparison functors of Fontaine. After rehearsing various versions of weights, we explain some more recent applications of weights, e.g., to Hasse principles and the computation of motivic cohomology, and discuss some open questions.
