Phase-Field Theory for FitzHugh–Nagumo-Type Systems
Pierpaolo Soravia, Panagiotis E. Souganidis · SIAM Journal on Mathematical Analysis · 1996
In this paper, we study the asymptotics of Fitzhugh–Nagumo-type systems of reaction-diffusion equations with bistable nonlinearity. In the limit, we obtain an interface moving with normal velocity determined by the dynamics and the scaling.
