Energy identity for stationary biharmonic mappings into spheres in supercritical dimensions
Chang-Yu Guo, Changyou Wang, Chang-Lin Xiang
Energy identity for harmonic type maps in supercritical dimensions is an important and difficult problem. For sphere-valued harmonic maps, the first breakthrough was achieved by Li…

Quantitative stratification and global regularity for 1/2-harmonic mappings
Changyu Guo, Guichun Jiang, Changyou Wang +2
In this paper, we extend the celebrated global regularity theory of Naber-Valtorta [Ann. Math. 2017] to 1/2-harmonic mappings into manifolds. Inspired by their work, we first adapt…
