Dynamics of one- and two-dimensional kinks in bistable reaction–diffusion equations with quasidiscrete sources of reaction
We study the evolution of fronts in a bistable reaction-diffusion system when the nonlinear reaction term is spatially inhomogeneous. This equation has been used to model wave propagation in various biological systems. Extending previous works on homogeneous reaction terms, we derive asymptotically an equation governing the front motion, which is …
