Abstract:

We prove a convexity property of the surface tension of non local, anisotropic free energy functionals which implies that the Wulff shape is strictly convex and smooth. We also prove that the transport coefficients of the limit anisotropic motion by mean curvature obtained in \cite{KS} are strictly positive and equal to the stiffness parameters determined by the surface tension.
