Asymptotic stability of the Boltzmann equation with Maxwell boundary conditions
Résumé
In a general C 1 domain, we study the perturbative Cauchy theory for the Boltzmann equation with Maxwell boundary conditions with an accommodation coefficient α in (2/3, 1], and discuss this threshold. We consider polynomial or stretched exponential weights m(v) and prove existence, uniqueness and exponential trend to equilibrium around a global Maxwellian in L ∞ x,v (m). Of important note is the fact that the methods do not involve contradiction arguments.
