Abstract:A boundary value problem for the stationary nonlinear Boltzmann equation in a slab has been examined in a weightedL infin space. It has been proved that the problem possesses a unique solution for boundary data small enough. The proof is based on the implicit function theorem. It has also been shown that for the linearized problem the Fredholm alternative applies.
Keywords:Boltzmann equation  boundary value problem  kinetic theory
