泛 Jacobian 的热带化

Tropicalization of the universal Jacobian

Margarida Melo, Samouil Molcho, Martin Ulirsch, Filippo Viviani

AI总结:

本文提供了栈理论框架研究热带曲线模空间上的泛热带 Jacobian,从对数与非阿基米德解析角度证明泛紧化 Jacobian 的热带化即为泛热带 Jacobian,且热带化映射与重言态射相容。

摘要:

在本文中,我们提供了一个栈理论框架,用于研究热带曲线模空间上的泛热带 Jacobian。我们开发了两种方法来研究曲线模空间上的泛紧化 Jacobian 的热带化过程——一种从对数角度,另一种从非阿基米德解析角度。从这两个角度得出的核心结果是,泛紧化 Jacobian 的热带化即为泛热带 Jacobian,并且这两种背景下的热带化映射与重言态射相容。在续篇中,我们将使用本文开发的技术为对数 Picard 簇提供显式的多面体模型。

英文摘要:

In this article we provide a stack-theoretic framework to study the universal tropical Jacobian over the moduli space of tropical curves. We develop two approaches to the process of tropicalization of the universal compactified Jacobian over the moduli space of curves -- one from a logarithmic and the other from a non-Archimedean analytic point of view. The central result from both points of view is that the tropicalization of the universal compactified Jacobian is the universal tropical Jacobian and that the tropicalization maps in each of the two contexts are compatible with the tautological morphisms. In a sequel we will use the techniques developed here to provide explicit polyhedral models for the logarithmic Picard variety.
