Bellettini, G.; Paolini, M. Anisotropic motion by mean curvature in the context of Finsler geometry. (English) Zbl 0873.53011 Hokkaido Math. J. 25, No. 3, 537-566 (1996). Author’s abstract: “We study the anisotropic motion of a hypersurface in the context of the geometry of Finsler spaces. This amounts to considering the evolution in relative geometry, where all quantities are referred to the given Finsler metric \(\phi\) representing the anisotropy, which we allow to be a function of space. Assuming that \(\phi\) is strictly convex and smooth, we prove that the natural evolution law is of the form ‘velocity \(=H_\phi\)’, where \(H_\phi\) is the relative mean curvature vector of the hypersurface. We derive this evolution law using different approaches, such as the variational method of Almgren-Taylor-Wang, the Hamilton-Jacobi equation, and the approximation by means of a reaction-diffusion equation”.
