Conservative forms of Boltzmann's collision operator: Landau revisited
École Normale Supérieure, DMI,
45 rue d'Ulm, 75230 Paris Cedex 05, France.
We show that Boltzmann's collision operator can be written explicitly in divergence and double divergence forms. These conservative formulations may be of interest for both theoretical and numerical purposes. We give an application to the asymptotics of grazing collisions.
