我们考虑I型Ricci流,并获得有效的曲率张量的积分估计,并包括奇异时间。我们的估计部分地扩展到更高的维度,Kleiner和Lott最近证明曲率估计在三维中保持不变(Acta Math 219(1):65-134,2017)。为此,我们采用了Cheeger-Naber(Invent Math 191(2):321-339,2013)介绍的定量分层技术。
We consider Type I Ricci flows and obtain integral estimates for the curvature tensor valid up to, and including, the singular time. Our estimates partially extend to higher dimensions a curvature estimate recently shown to hold in dimension three by Kleiner and Lott (Acta Math 219(1):65-134, 2017). To do this we adapt the technique of quantitative stratification, introduced by Cheeger-Naber (Invent Math 191(2):321-339, 2013), to this setting.
