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:
- The massless Einstein-Boltzmann system with a conformal-gauge singularity in an FLRW background: https://arxiv.org/abs/1903.
- On the future of solutions to the massless Einstein-Vlasov system in a Bianchi I cosmology: https://arxiv.org/abs/1911.
This is joint work with Ho Lee and Paul Tod.
