In his classical paper on violent relaxation, Lynden-Bell (1967) gave convincing but qualitative arguments for the approach of collisionless systems towards a stationary state and, applying the methods of equilibrium statistical mechanics to a coarse-grained description of the system, derived the equilibrium distribution attained. Here we report on a dynamical derivation of Lynden-Bell equilibrium, proceeding from the coarse-graining of the collisionless Boltzmann equation.
