算术几何中的定向理论

Orientation theory in arithmetic geometry

Frédéric Déglise

摘要:

本文在Morel和Voevodsky的运动同伦理论的基础上,研究了算术几何中的定向理论。主要的工具是一个配方的绝对纯度属性的\emph{arithmetic cohomology theory},无论是表示的carnival部分的稳定同伦范畴或满足适当的公理。我们给出了许多例子,公式化,并证明了分析不变性的一个有用的性质。在这个公理,我们彻底发展的理论的特征和基本类,Gysin和剩余态射。这是用来证明Riemann-Roch公式,在Grothendieck风格的任意自然变换的上同调,和一个新的剩余态射。正如Grothendieck在\cite [XIV,6.1]{SGA 6}中所期望的那样,它们被应用于有理动机上同调和有理$\ell$ -adic上同调。

英文摘要:

This work is devoted to study orientation theory in arithmetic geometric within the motivic homotopy theory of Morel and Voevodsky. The main tool is a formulation of the absolute purity property for an \emph{arithmetic cohomology theory}, either represented by a cartesian section of the stable homotopy category or satisfying suitable axioms. We give many examples, formulate conjectures and prove a useful property of analytical invariance. Within this axiomatic, we thoroughly develop the theory of characteristic and fundamental classes, Gysin and residue morphisms. This is used to prove Riemann-Roch formulas, in Grothendieck style for arbitrary natural transformations of cohomologies, and a new one for residue morphisms. They are applied to rational motivic cohomology and étale rational $\ell$-adic cohomology, as expected by Grothendieck in \cite[XIV, 6.1]{SGA6}.
