In this paper we prove the convergence of a suitable particle system towards
the BGK model. More precisely, we consider an interacting stochastic particle
system in which each particle can instantaneously thermalize locally...We show
that, under a suitable scaling limit, propagation of chaos does hold and that
the one-particle distribution function converges to the solution of the BGK
equation.(read more)
