DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VMAS/26/">Dy
 namical fluctuations of a hard sphere gas in the low density limit</a>\nby
  Laure Saint-Raymond (IHES) as part of Virtual Maxwell Analysis Seminar\n\
 n\nAbstract\nThe dynamics of a hard sphere gas is described in the low den
 sity limit by the Boltzmann equation\, at least for short times.\n\nThe cl
 assical strategy  of proof\, due to Lanford\, fails for longer times\, eve
 n close to equilibrium.\n\nIn this talk\, I will present a recent work wit
 h T. Bodineau\, I. Gallagher and S. Simonella\, where we  have  designed a
  new method\, combining a duality and  a pruning arguments\, which allows 
  to characterize the fluctuations around equilibrium globally in time.\n
