Kahler锥度量空间中的测地线,II。常数量曲率Kahler锥度量的唯一性

Geodesics in the space of Kahler cone metrics, II. Uniqueness of constant scalar curvature Kahler cone metrics

Kai Zheng

摘要:

这是以前关于Kahler锥度量的文章的延续。在这篇文章中,我们引入了加权函数空间,并提供了一个完整的处理锥角在整个区间$(0,1]$。我们首先在Kahler锥度量(锥测地线)空间中构造测地线。接下来,我们确定非常详细的渐近行为的常数数量曲率卡勒(cscK)锥度量,这导致了约化的自同构群。然后我们建立了Lichnerowicz算子的线性理论,这直接意味着使cscK锥度量的锥角变形的路径的开放性。最后,我们解决了cscK锥度量的唯一性问题,并证明了cscK锥度量在自同构下是唯一的。

英文摘要:

This is a continuation of the previous articles on Kahler cone metrics. In this article, we introduce weighted function spaces and provide a self-contained treatment on cone angles in the whole interval $(0,1]$. We first construct geodesics in the space of Kahler cone metrics (cone geodesics). We next determine the very detailed asymptotic behaviour of constant scalar curvature Kahler (cscK) cone metrics, which leads to the reductivity of the automorphism group. Then we establish the linear theory for the Lichnerowicz operator, which immediately implies the openness of the path deforming the cone angles of cscK cone metrics. Finally, we address the problem on the uniqueness of cscK cone metrics and show that the cscK cone metric is unique up to automorphisms.
