SUMMARY:Perturbative regimes for deterministic dynamics of a diluted gas o
 f hard spheres - Thierry Bodineau (École Polytechnique)

DESCRIPTION:We consider a dilute gas of hard spheres evolving according to
  Newtonian dynamics and starting close to equilibrium. We will show that\,
  in the Boltzmann Grad limit\, the linear and linearized Boltzmann equatio
 ns can be recovered up to any large time. As a consequence\, we prove that
  a tagged particle behaves as a Brownian motion after rescaling.
