仿射厄米-爱因斯坦算符

Affine Hermitian-Einstein Metrics

John Loftin

摘要:

我们发展了一个特殊仿射流形上平坦向量丛的稳定丛和仿射Hermitian-Einstein度量的理论。本文给出了一个类似于Donaldson-Uhlenbeck-Yau关于Kähler流形上Hermitian-Einstein度量存在性的证明,以及Li-Yau将这个定理推广到Gauduchon度量的非Kähler复情形。我们的稳定性定义只涉及平坦向量子丛(而不是奇异子层),因此在某些地方比复情形简单。

英文摘要:

We develop a theory of stable bundles and affine Hermitian-Einstein metrics for flat vector bundles over a special affine manifold (a manifold admitting an atlas whose gluing maps are all locally constant volume-preserving affine maps). Our paper presents a parallel to Donaldson-Uhlenbeck-Yau's proof of the existence of Hermitian-Einstein metrics on Kähler manifolds, and the extension of this theorem by Li-Yau to the non-Kähler complex case of Gauduchon metrics. Our definition of stability involves only flat vector subbundles (and not singular subsheaves), and so is simpler than the complex case in some places.
