DESCRIPTION:Title: <a href="https://researchseminars.org/talk/DSandPDEs/7/
 ">On the derivation of the Boltzmann equation: fluctuations and large devi
 ations</a>\nby Isabelle Gallagher (École Normale Supérieure) as part of 
 Dynamical systems and PDEs\n\n\nAbstract\nIt has been known since Lanford
 ’s result in 1974 that in the limit when the number of particles goes to
  infinity in a rarefied gas\, the one-particle distribution satisfies the 
 Boltzmann equation\, at least for a short time. In this talk we shall anal
 yze the fluctuations\, and large deviations around that limit. This corres
 ponds to joint works with Thierry Bodineau\, Laure Saint-Raymond and Sergi
 o Simonella.\n
