    On the evolution of the empirical measure for the hard-sphere dynamics
    (Berlin : Weierstraß-Institut für Angewandte Analysis und Stochastik, 2015) Pulvirenti, Mario; Simonella, Sergio
    We prove that the evolution of marginals associated to the empirical measure of a finite system of hard spheres is driven by the BBGKY hierarchical expansion. The usual hierarchy of equations for L1 measures is obtained as a corollary. We discuss the ambiguities arising in the corresponding notion of microscopic series solution to the Boltzmann-Enskog equation.
