The spatially homogeneous Boltzmann equation for massless particles in an FLRW background

We study the spatially homogeneous relativistic Boltzmann equation for massless particles in an FLRW background with scattering kernels in a certain range of soft and hard potentials. We obtain the future global existence of small solutions in a weighted L1 ∩ L∞ space.
