扭曲Higgs束的平衡度规

Balanced metrics on twisted Higgs Bundles

Mario Garcia-Fernandez, Julius Ross

摘要:

Kähler流形$X$上的扭曲Higgs丛是由全纯向量丛$E$和某个全纯向量丛$M$的全纯丛态射$ϕ\colon M\otimes E \to E$组成的对$(E,ϕ)$。当$X$是一条曲线,$M$是$X$的切丛时,Hitchin首先考虑了这样的对象,Simpson也考虑了高维基。希钦-小林对应表明$(E,ϕ)$是多稳定的当且仅当$E$允许一个厄密度量解希钦方程。这种对应关系是判断方程是否存在解的有力工具,但它提供的关于实际解的信息很少。在本文中,我们研究了这个问题的量化表示在有限维数据和平衡度量,使近似解希钦方程。本研究的动机来自Donagi-Wijnholt在arXiv:1104.2610上关于Vafa-Witten方程的平衡度量的工作。

英文摘要:

A twisted Higgs bundle on a Kähler manifold $X$ is a pair $(E,ϕ)$ consisting of a holomorphic vector bundle $E$ and a holomorphic bundle morphism $ϕ\colon M\otimes E \to E$ for some holomorphic vector bundle $M$. Such objects were first considered by Hitchin when $X$ is a curve and $M$ is the tangent bundle of $X$, and also by Simpson for higher dimensional base. The Hitchin-Kobayashi correspondence for such pairs states that $(E,ϕ)$ is polystable if and only if $E$ admits a hermitian metric solving the Hitchin equation. This correspondence is a powerful tool to decide whether there exists a solution of the equation, but it provides little information as to the actual solution. In this paper we study a quantization of this problem that is expressed in terms of finite dimensional data and balanced metrics that give approximate solutions to the Hitchin equation. Motivation for this study comes from work of Donagi--Wijnholt on arXiv:1104.2610 concerning balanced metrics for the Vafa-Witten equations.
