SUMMARY: (...): Acceleration in reaction-diffusion equations
DESCRIPTION:: Widely used in mathematical biology\, reaction-diffusion equa
 tions\, and in particular the Fisher-KPP equation\, are used to model the 
 spreading of a population through a new environment.  The earliest results
  showed that populations moved at a constant speed (i.e. linear in time). 
  However\, about five years ago\, Hamel and Roques discovered acceleration
 \, or super-linear in time propagation of the population\, when the initia
 l population is very spread out.  Over the last few years\, acceleration h
 as been discovered in a number of other settings.  In this talk\, I will d
 iscuss several of these settings\, with the aim of developing an intuition
  for what causes and what blocks acceleration.  The work in this talk is j
 oint with Emeric Bouin and Lenya Ryzhik.http://perso.ens-lyon.fr/christoph
