DESCRIPTION:The statistics at the tip of a branching random walk can be st
 udied using the Fisher-KPP equation. The whole limiting measure\, at the t
 ip\, can be understood in terms of the way the delay of a traveling wave s
 olution of the F-KPP equation depends on its initial condition. Several an
 alytical properties of the distribution of the distances between the right
 most particles can be predicted. This work was motivated by the study of t
 he statistical properties of genealogies of evolving populations under sel
 ection. \n\n\nhttp://www.lps.ens.fr/~derrida/
