Kähler度量流的切流

Tangent Flows of Kähler Metric Flows

Max Hallgren, Wangjian Jian

摘要:

本文改进了Kähler环境下非塌陷里奇流的$\mathbb{F}$ -极限的描述.特别地,这种度量流的奇异层$\mathcal{S}^k$满足$\mathcal{S}^{2j}=\mathcal{S}^{2j+1}$。我们还证明了一个类似的结果定量地层,并表明,任何切流承认一个非平凡的单参数作用的等距,这是局部自由的锥链接在静态的情况下。主要结果是建立使用抛物正则化的共轭热核势函数基于几乎自相似点,这可能是独立的利益。

英文摘要:

We improve the description of $\mathbb{F}$-limits of noncollapsed Ricci flows in the Kähler setting. In particular, the singular strata $\mathcal{S}^k$ of such metric flows satisfy $\mathcal{S}^{2j}=\mathcal{S}^{2j+1}$. We also prove an analogous result for quantitative strata, and show that any tangent flow admits a nontrivial one-parameter action by isometries, which is locally free on the cone link in the static case. The main results are established using parabolic regularizations of conjugate heat kernel potential functions based at almost-selfsimilar points, which may be of independent interest.
