报告摘要:We study the Boltzmann equation without angular cutoff in the perturbation setting. By the macro-micro decomposition and hypoelliptic techniques, we obtain uniform (with respect to large time) estimate on radius of spatial analyticity or Gevrey class regularity. We hope this may give insight on the regularity transition in the hydrodynamic limit of Boltzmann equation.
