Long-time derivation at equilibrium of the fluctuating Boltzmann equation
Thierry Bodineau, Isabelle Gallagher, Laure Saint-Raymond +1
We study a hard sphere gas at equilibrium, and prove that in the low density limit, the fluctuations converge to a Gaussian process governed by the fluctuating Boltzmann equation.…
