Irreversibility in gas dynamics

Irreversibility in gas dynamics
Laure Saint-Raymond
École Normale Supérieure
At the atomistic level, a gas can be described by a (reversible) Hamiltonian system of
ODEs. However the macroscopic evolution has an entropy which is an increasing
function of time. The goal of this lecture is to point out where the irreversibility
shows up in the derivation of the Boltzmann equation.
