Gromov–Hausdorff limits of Kähler manifolds with Ricci curvature bounded below Ricci曲率有界以下的Kähler流形的Gromov-Hausdorff极限
IF 2.2 1区 数学 Q1 Mathematics Pub Date : 2022-03-28 DOI: 10.1007/s00039-022-00594-8
Gang Liu, Gábor Székelyhidi

We show that non-collapsed Gromov–Hausdorff limits of polarized Kähler manifolds, with Ricci curvature bounded below, are normal projective varieties, and the metric singularities of the limit space are precisely given by a countable union of analytic subvarieties. This extends a fundamental result of Donaldson–Sun, in which 2-sided Ricci curvature bounds were assumed. As a basic ingredient we show that, under lower Ricci curvature bounds, almost Euclidean balls in Kähler manifolds admit good holomorphic coordinates. Further applications are integral bounds for the scalar curvature on balls, and a rigidity theorem for Kähler manifolds with almost Euclidean volume growth.

我们证明了具有Ricci曲率下界的极化Kähler流形的非坍缩Gromov-Hausdorff极限是正规的射影变体,并且极限空间的度量奇点是由解析子变体的可数并精确给出的。这扩展了Donaldson-Sun的一个基本结果,其中假设了双面Ricci曲率边界。作为一个基本成分,我们证明了在下里奇曲率界下,Kähler流形中的几乎欧几里得球承认良好的全纯坐标。进一步的应用是球上标量曲率的积分界,以及几乎具有欧几里得体积增长的Kähler流形的刚性定理。
