Relaxation Approximations to Front Propagation

Shi Jin and Marcos Katsoulakis

Abstract: We introduce a relaxation model for front propagation problems. Our proposed relaxation approximation is a semilinear hyperbolic system without singularities. It yields a direction-dependent normal velocity at the leading term and captures, in the Chapman-Enskog expansion, the higher curvature dependent correction, including possible anisotropies.
