On the massless Einstein-Boltzmann system

There are several recent important results concerning the massless Einstein-Vlasov system such as the stability of Minkowski space or the stability of De Sitter spacetime. In this talk I will present some recent progress on the massless Einstein-Boltzmann system in both directions, initial singularity and long time behaviour:

This is joint work with Ho Lee and Paul Tod.
