Query: Global regularity estimates for the Boltzmann equation without cut-off   We derive $C^\infty$ a priori estimates for solutions of the inhomogeneous
Boltzmann equation without cut-off, conditional to point-wise bounds on their
mass, energy and entropy densities. We also establish decay estimates for large
velocities, for all derivatives of the solution.
