Abstract:

After reviewing the progress on the Boltzmann equation without angular cutoff in recent years both on spatially homogeneous and inhomogeneous Boltzmann equation, I will present two results. One is about the regularizing effect of the homogeneous Boltzmann equation with Debye-Yukawa potential for measure valued solutions.

Another one is about the well-posedness of perturbative solution to the inhomogeneous Boltzmann equation when the initial perturbation has only algebraic decay in the velocity variable.
