Abstract:
We consider the Einstein--Boltzmann system for massless/massive particles in the Bianchi I spacetime with scattering cross-sections in a certain range of soft potentials. We assume that the spacetime has an initial conformal gauge singularity and show that the initial value problem is well posed with data given at the singularity.
