Abstract
We introduce a relaxation model for front propagation problems. Our pr oposed relaxation approximation is a semilinear hyperbolic system with out singularities. It yields a direction-dependent normal velocity at the leading term and captures, in the Chapman-Enskog expansion, the hi gher order curvature dependent corrections, including possible anisotr opies.
