“The many faces of the Fisher-KPP equation”
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
After a short review, this talk will try to present several recent results.
