DESCRIPTION:Speaker: Julien Berestycki\nhosted by M. Beiglböck\, N. Berest
 ycki\, L. Erdös\, J. Maas\nAbstract: The "Brownian bees" model is a parti
 cle system in $\\R^d$ in which particles move independently as Brownian mo
 tions\, branch at rate one and the total population size is kept constant 
 equal to N by removing the particle with maximum distance to the origin at
  each branching event. This type of spatial branching process with selecti
 on and its variants (such as the N-BBM) are simple models for the evolutio
 n of populations under selection. In this talk\, I'll show how the large s
 cale behaviour of these systems is given by the solutions of certain Free-
 boundary problems and how this can (or can't) be used to understand their 
 large time behaviour.This is based on joint works in progress with E. Brun
 et\, J. Nolen and S. Penington.
