Abstract

The paper is concerned with heat flow for the square root of the negative Laplacian for unit length vectors, motivated by the model of DeSimone, Kohn, Otto and Müller. We show the existence of weak solutions for the periodic case by means of the penalty approximation and commutator estimate.
