Uniqueness and Regularity of the Fractional Harmonic Gradient Flow in $S^{n-1}$

Abstract

In this paper, we study the fractional harmonic gradient flow on $S^1$ taking values in $S^{n-1}\subset {\mathbb{R}}^n$ for every $n\ge 2$, in particular addressing uniqueness and regularity of solutions in the so-called energy class with sufficiently small energy, adding to the existing body of knowledge which includes existence of solutions and certain bubbling phenomena.
