本文的目的是研究Rapoport-Zink的权谱序列的某些性质的特殊化的论点。通过减少到Deligne以前处理的有限域上的情况下,我们证明了定义在l-adic etale上同调的权过滤和monodromy过滤一致,直到移位,对于相等特征局部域上的真光滑簇。我们还证明了在E2退化的重量谱序列的任何特征,而不使用日志几何。此外,作为一个应用程序,我们给一个模p 0减少证明霍奇模拟以前考虑Steenbrink。
The aim of this paper is to study certain properties of the weight spectral sequences of Rapoport-Zink by a specialization argument. By reducing to the case over finite fields previously treated by Deligne, we prove that the weight filtration and the monodromy filtration defined on the l -adic etale cohomology coincide, up to shift, for proper smooth varieties over equal characteristic local fields. We also prove that the weight spectral sequences degenerate at E 2 in any characteristic without using log geometry. Moreover, as an application, we give a modulo p 0 reduction proof of a Hodge analogue previously considered by Steenbrink.
