Event details

The Fisher KPP equation describes the growth of a stable region into an unstable medium. It was introduced in 1937 both by the biologist and statistician Fisher and by the mathematicians Kolmogorov, Petrovsky, Piscounov to model the propagation of a favorable gene in a population. It is one of the  classical examples of the problem  of velocity selection.  It  also appears  in many other contexts, ranging from the  theory of disordered systems and spin glasses to  reaction diffusion problems, branching Brownian motion  and models of evolution with selection.  

After a short review, this talk will try to present several recent results.
