算术Hodge指标定理与函数域上动力系统的刚性

The arithmetic Hodge Index Theorem and rigidity of dynamical systems over function fields

Alexander Carney

摘要:

在阿拉克洛夫算术相交理论的基本结果之一中,Faltings和Hriljac(独立地)通过将相交配对与Néron-Tate高度配对的负值联系起来,证明了算术曲面的霍奇指数定理。最近,Moriwaki和Yuan-Zhang将其推广到更高的维度。在这项工作中,我们将这些结果推广到超越度为1的函数域上的投影簇。新的挑战是处理非恒定的,但数值平凡的线丛来自常量域通过周的$K/k$跟踪函子。作为Hodge指标定理的应用,我们还证明了函数域上极化代数动力系统的标准高度零点集的刚性定理。对于有限域上的函数域,本文给出了预周期点的刚性定理,推广了Mimar,Baker-DeMarco和张元的工作.

英文摘要:

In one of the fundamental results of Arakelov's arithmetic intersection theory, Faltings and Hriljac (independently) proved the Hodge Index Theorem for arithmetic surfaces by relating the intersection pairing to the negative of the Néron-Tate height pairing. More recently, Moriwaki and Yuan-Zhang generalized this to higher dimension. In this work, we extend these results to projective varieties over transcendence degree one function fields. The new challenge is dealing with non-constant but numerically trivial line bundles coming from the constant field via Chow's $K/k$-trace functor. As an application of the Hodge Index Theorem, we also prove a rigidity theorem for the set of canonical height zero points of polarized algebraic dynamical systems over function fields. For function fields over finite fields, this gives a rigidity theorem for preperiodic points, generalizing previous work of Mimar, Baker-DeMarco, and Yuan-Zhang.
