Classical Inequalities for the Boltzmann Collision Operator

Ricardo Alonso
University of Texas at Austin

We present an study of the integrability properties of a more general version of the Boltzmann collision operator that includes inelastic interactions between particles. We will show proofs of a Young’s inequality estimate for the case of hard potentials, a Hardy-Littlewood-Sobolev inequality estimate for soft potentials, and an estimate with Maxwellian weights for hard potentials. The main technique used to derive the results is the radial average symmetrization.
