关于零级Higgs-de Rham流的一个注记

A note on Higgs-de Rham flows of level zero

Mao Sheng, Jilong Tong

摘要:

Higgs-de Rham流的概念由Lan-Sheng-Zuo提出,作为复非交换Hodge理论中Yang-Mills-Higgs流的类似物。在这篇短文中,我们研究了这个理论的一小部分,并研究了零级的希格斯-德拉姆流。我们改进了零级Higgs-de Rham流的原始定义(适用于一般水平),并建立了零级Higgs-de Rham流与基本群的某些正特征表示之间的Hitchin-Simpson型对应,推广了Katz的经典结果.我们比较了对应中两边的形变理论,并将Galois作用于定义在有限域上的代数簇的几何基本群上的作用量转化到Higgs一边。

英文摘要:

The notion of Higgs-de Rham flows was introduced by Lan-Sheng-Zuo, as an analogue of Yang-Mills-Higgs flows in the complex nonabelian Hodge theory. In this short note we investigate a small part of this theory, and study those Higgs-de Rham flows which are of level zero. We improve the original definition of level-zero Higgs-de Rham flows (which works for general levels), and establish a Hitchin-Simpson-type correspondence between such objects and certain representations of fundamental groups in positive characteristic, which generalizes the classical results of Katz. We compare the deformation theories of two sides in the correspondence, and translate the Galois action on the geometric fundamental groups of algebraic varieties defined over finite fields into the Higgs side.
