Abstract:
The connection between reaction-diffusion PDEs of the KPP type and branching particle processes (such as the branching Brownian motion) is well known and has been extensively studied. In this talk, I will present several recent results which concern branching particle systems with selection (in which the number of particles is kept constant) and their relationship with a class of free boundary problems.
Based on joint works with Eric Brunet, Bernard Derrida, Sarah Penington and Jim Nolen.
