$p$-adic域上的Weil-étale上同调

Weil-étale Cohomology over $p$-adic Fields

David A. Karpuk

摘要:

我们建立对偶结果的上同调的韦伊组的$p$-进字段,类似,但更一般的,结果从伽罗瓦上同调。我们证明了离散Weil模的一个对偶定理,它蕴涵着Tate-Nakayama对偶。定义了局部域上簇的Weil-光滑上同调,并证明了PDMATHAMN在具有有理点的光滑真曲线上的上同调的对偶定理。这最后一个定理是类似的,并暗示,一个经典的对偶定理,这样的曲线。

英文摘要:

We establish duality results for the cohomology of the Weil group of a $p$-adic field, analogous to, but more general than, results from Galois cohomology. We prove a duality theorem for discrete Weil modules, which implies Tate-Nakayama Duality. We define Weil-smooth cohomology for varieties over local fields, and prove a duality theorem for the cohomology of $\G_m$ on a smooth, proper curve with a rational point. This last theorem is analogous to, and implies, a classical duality theorem for such curves.
