Query: Propagation of Gevrey regularity for solutions of the Boltzmann equation
  for Maxwellian molecules   We prove that Gevrey regularity is propagated by the Boltzmann equation with
Maxwellian molecules, with or without angular cut-off. The proof relies on the
Wild expansion of the solution to the equation and on the characterization of
Gevrey regularity by the Fourier transform.
