The effect of a cutoff on pushed and bistable fronts of the reaction diffusion equation
arXiv:nlin/0703064 · doi:10.1103/PhysRevE.76.051101
Abstract
We give an explicit formula for the change of speed of pushed and bistable fronts of the reaction diffusion equation when a small cutoff is applied at the unstable or metastable equilibrium point. The results are valid for arbitrary reaction terms and include the case of density dependent diffusion.
