Séminaire

Acceleration of Fisher-KPP propagation in the case of reaction and diffusion heterogeneities




Date(s) : 05/04/2016   iCal
10h00 - 11h00

In this talk I will present some new propagation phenomena in the context of reaction-diffusion systems of Fisher-KPP type, which model the dynamics of a population in a 2 dimensional environment with one or more lines of fast diffusion. I will also consider the effect of reaction heterogeneities, again in 1D-2D cases, but also in 2D-2D ones.

These works have been obtained in collaboration with L. Rossi (EHESS, Paris) and E. Valdinoci (WIAS, Berlin).
