V.I. Gerasimenko On Derivation of Kinetic Equations for Granular Media: Brief Survey (423K, PDF) ABSTRACT. A new approach to the rigorous derivation of a priori kinetic equations from the dynamics of inelastically colliding particles, namely, the Enskog-type and Boltzmann-type kinetic equations describing granular media, is reviewed. The problem of potential possibilities inherent in describing the evolution of the states of a system of many hard spheres with inelastic collisions by means of a one-particle distribution function is also considered.
