Optimal Higher Regularity for Biharmonic Maps Via Quantitative Stratification
摘要
This note is devoted to refining the almost optimal regularity results of Breiner and Lamm on minimizing and stationary biharmonic maps via the powerful quantitative stratification method initiated by Cheeger and Naber and significantly developed by Naber and Valtorta for harmonic maps. In particular, we obtain an optimal regularity result for minimizing biharmonic maps.
