RESUMO
With the help of simple probabilistic models of Kac and McKean, we discuss the meaning of the generalized expression for entropy that was recently introduced by our group and compare it with Boltzmann's expression. We emphasize the fact that Boltzmann's formulation in terms of the single particle distribution function, f1, requires very restricted assumptions about the preparation of the system (chaos) and the nature of the collision mechanism (Markov processes).
