C. Mouhot, L. Silvestre and myself just uploaded on HAL and arXiv a new preprint entitled Decay estimates for large velocities in the Boltzmann equation without cut-off.
Abstract: We establish pointwise large velocity decay rates for the solution of the inhomogeneous Boltzmann equation without cutoff, under the assumption that three hydrodynamic quantities (mass, energy, entropy densities) stay under control.
