Green's function techniques for studying nonequilibrium quantum processes are discussed. Perturbation expansions and Green's function equations of motion are developed for noncorrelated and correlated initial states of a system. A transition, from the KadanoffBaym Green's function equations of motion to the Boltzmann equation, and specifications of the respective limit, are examined in detail.
