Yu He, ChangLin Xiang, GaoFeng Zheng

AI总结:

本文针对球值分数阶调和映射,利用 Cheeger-Naber 定量微分方法建立奇异集的定量分层理论,从而获得全局正则性估计。

摘要:

本文考虑近年来由多位作者引入的球值稳态/极小化分数阶调和映射,尤其是 Millot-Pegon-Schikorra 和 Millot-Sire 的工作。基于他们丰富的部分正则性理论,我们利用 Cheeger-Naber 的定量微分方法,为这些映射的奇异集建立了一个定量分层理论,并由此得到全局正则性估计。

英文摘要:

In this paper we consider sphere-valued stationary/minimizing fractional harmonic mappings introduced in recent years by several authors, especially by Millot-Pegon-Schikorra \cite{Millot-Pegon-Schikorra-2021-ARMA} and Millot-Sire \cite{Millot-Sire-15}. Based on their rich partial regularity theory, we establish a quantitative stratification theory for singular sets of these mappings by making use of the quantitative differentiation approach of Cheeger-Naber \cite{Cheeger-Naber-2013-CPAM}, from which a global regularity estimates follows.
