Partial regularity of heat flow of fractional harmonic maps to spheres

Hengrong Du, Tao Huang, Armin Schikorra +1

In this paper, we introduce the notation of stationary heat flow of $s$-harmonic maps from ${\mathbb{R}}^m$ into the unit sphere ${\mathbb{S}}^{\ell -1}\hookrightarrow {\mathbb{R}}^{\ell }$, for $0<…
