Statistical Description of Hard Sphere Gas Dynamics
Abstract: We are going to discuss the key role played by propagation of chaos in the derivation of Boltzmann equation from particle systems. In the case of deterministic (reversible) hard-sphere dynamics, we will see that the emergence of the irreversibility in the kinetic limit is related to singular correlations created by the Hamiltonian dynamics. The fluctuations around the Botzmann equation can be analyzed thanks to the control of the dynamical correlations.
Everyone is invited! Join us for coffee and tea in the common room (B448) half an hour before the talk.
