CLASSICAL LIMIT OF THE GENERATING FUNCTIONAL FOR THE NONEQUILIBRIUM STATISTICAL-MECHANICS

By using the path integral representation of the double path generating functional W[j1/j2] for the non-equilibrium statistical mechanics, the classical limit of W is discussed. Through the appropriate choice of the factor h, the finite limit of Wis shown to exist, thereby obtaining the explicit form of the classical non-equilibrium generating functional. The classical limit of the Legendre transformed generating functional Γ is also discussed. © 1990, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
