    The influence of a line with fast diffusion on Fisher-KPP propagation

    We propose a new system to describe the effect of a "road" with fast
    diffusion on biological invasions. Outside of the road a classical
    Fisher-KPP propagation takes place. It is found that the presence of
    the road enhances the global propagation only after an explicit
    threshold for the ratio of the diffusivities on and outside the
    road. The cases where transport and mortality take place on the road
    are further discussed. This is a joint work with H. Berestycki and
    J.-M. Roquejoffre.
