Global existence and full regularity of the Boltzmann equation without angular cutoff

Radjesvarane Alexandre, Y. Morimoto, Seiji Ukai +2

We prove the global existence and uniqueness of classical solutions around an equilibrium to the Boltzmann equation without angular cutoff in some Sobolev spaces. In addition, the…

Regularizing effect and local existence for non-cutoff Boltzmann equation

Radjesvarane Alexandre, Y. Morimoto, Seiji Ukai +2

The Boltzmann equation without Grad's angular cutoff assumption is believed to have regularizing effect on the solution because of the non-integrable angular singularity of the cro…
