Abstract

This article proves the regularity for the Boltzmann equation without angular cutoff with hard potential. By sharpening the coercivity and upper bound estimate on the collision operator, analyzing the Poisson bracket between the transport operator and some weighted pseudodifferential operator, we prove the regularizing effect in space and velocity variables when the initial data have mild regularity.
