Abstract
We consider a nonlinear transport equation as a hyperbolic generalisation of the well-known reaction diffusion equation. We show the existence of strictly monotone travelling fronts for the three main types of the nonlinearity: the positive source term, the combustion law, and the bistable case. In the first case there is a whole interval of possible speeds containing its strictly positive minimum For subtangential nonlinearities we can express the minimal wave speed explicitly by a variational formula.
