The talk will be devoted to phase field approximations of multiphase mean curvature flows which can incorporate anisotropic surface tensions and mobility coefficients. The model we propose is well suited for both purposes of asymptotic analysis and derivation of a robust numerical scheme. Several numerical examples will be provided, related either to physics or imaging.
