摘要
We show that a regularized stationary Boltzmann equation with diffusive boundary conditions can be rigorously derived from a suitable stochastic N-particle system. To do this, we prove that the L-1-distance between the k-particle density and the k-fold product of the solution to the stationary Boltzmann equation is of order 1/N.
