<h2>The influence of a line with fast diffusion on Fisher-KPP
propagation<br>
<br>
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. </h2>
