ABSTRACT
In Chapter 1, we have described the states of systems of finitely many particles by probability distribution functions given on the phase space. In statistical mechanics, there exists another (equivalent) way of describing the states of systems of finitely many par ticles by sequences of so-called correlation («-particle distribution) functions. In this case, the evolution of the state is described by the solution of the Cauchy problem of the BBGKY (Bogolyubov-Bom-Green-Kirkwood-Yvon) hierarchy of equations.
