Dynamical fluctuations of a hard sphere gas in the low density limit

Abstract: The dynamics of a hard sphere gas is described in the low density limit by the Boltzmann equation, at least for short times.

The classical strategy of proof, due to Lanford, fails for longer times, even close to equilibrium.

In this talk, I will present a recent work with 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.
