回火基本群与Mumford曲线的度量图

Tempered fundamental group and metric graph of a Mumford curve

Emmanuel Lepage

摘要:

本文试图给出$p$ -adic光滑代数簇的调和基本群(它是p-adic世界中复代数簇的拓扑基本群的一种模拟)的一些一般性结果。主要结果表明,人们可以从Mumford曲线的调和基本群恢复Mumford曲线的稳定模型的图的度量结构。我们还将证明双有理不变性,代数封闭的扩展和Kuenneth公式的回火基本群的不变性。我们将描述交换阿贝尔簇的调和基本群,并将曲线的调和基本群与其雅可比簇的调和基本群联系起来。

英文摘要:

This paper is an attempt to give some general results on the tempered fundamental group of a $p$-adic smooth algebraic varieties (which is a sort of analog of the topologic fundamental group of complex algebraic varieties in the p-adic world). The main result asserts that one can recover the metric structure of the graph of the stable model of a Mumford curve from the tempered fundamental group of this Mumford curve. We will also prove birational invariance, invariance by algebraically closed extensions and a Kuenneth formula for the tempered fundamental group. We will describe the tempered fundamental group of an abelian variety and link the tempered fundamental group of a curve to the tempered fundamental group of its Jacobian variety.
