DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SIAM-PDE/4/"
 >Fluctuation theory in the Boltzmann-Grad limit</a>\nby Laure Saint-Raymon
 d (ENS Lyon\, France) as part of Seminar In the Analysis and Methods of PD
 E (SIAM PDE)\n\n\nAbstract\nIn this talk\, I will discuss a long term proj
 ect with T. Bodineau\, I. Gallagher and S. Simonella on hard-sphere gases.
  In the low density limit\, the empirical density obeys a law of large num
 bers and the dynamics is governed asymptotically by the (kinetic) Boltzman
 n equation. Deviations from this behavior are described by dynamical corre
 lations\, which we can fully characterize for short times. This provides b
 oth a fluctuating Boltzmann equation and large deviation asymptotics.\n
