Abstract

In this paper, motivated by [16], we use the Littlewood-Paley theory to establish some estimates on the nonlinear collision term, which enable us to investigate the Cauchy problem of the Fokker-Planck-Boltzmann equation. When the initial data is a small perturbation of the Maxwellian equilibrium state, under the Grad's angular cutoff assumption, the unique global solution for the hard potential case is obtained in the Besov-Chemin-Lerner type spaces C([0, ∞); L~ξ 2(B2,r s)) with 1 ≤ r ≤ 2 and s > 3/2 or s = 3/2 and r = 1. Besides, we also obtain the uniform stability of the dependence on the initial data.
