Super Ricci 流空间的紧性理论

Compactness theory of the space of Super Ricci flows

Richard H Bamler

AI总结:

本文建立 super Ricci 流的紧性理论,证明适当带点序列子列收敛于 metric flow,并在局部曲率界下将极限分解为正则与奇异部分,为部分正则性理论奠定基础。

摘要:

我们建立了一套关于 super Ricci 流的紧性理论,为 [Bam20b] 中的部分正则性理论奠定基础。我们的结果表明:任何具有相同维数、并在适当意义下带点的 super Ricci 流序列,都存在子序列收敛到某种合成流,称为 metric flow(度量流)。我们将详细研究该极限流的几何与解析性质,以及这种收敛。我们还将看到,在适当的局部曲率界下,Ricci 流的极限可分解为正则部分与奇异部分。正则部分可被赋予典范的 Ricci flow spacetime(Ricci 流时空)结构,并且我们在正则部分的某个子集上得到光滑收敛。

英文摘要:

We develop a compactness theory for super Ricci flows, which lays the foundations for the partial regularity theory in [Bam20b]. Our results imply that any sequence of super Ricci flows of the same dimension that is pointed in an appropriate sense subsequentially converges to a certain type of synthetic flow, called a metric flow. We will study the geometric and analytic properties of this limiting flow, as well as the convergence in detail. We will also see that, under appropriate local curvature bounds, a limit of Ricci flows can be decomposed into a regular and singular part. The regular part can be endowed with a canonical structure of a Ricci flow spacetime and we have smooth convergence on a certain subset of the regular part.
