Summary: We discuss the Boltzmann equation in a slab, with boundary conditions of diffuse reflection and mass conservation at the wall, and assigned total mass (per unit area). We prove that there is at least one non-negative measure-valued solution. The physical model is provided by Maxwellian molecules with angular cutoff. The equation is rewritten after a change of variables which is shown to be invertible.
