In a previous paper a new derivation of the Langevin equations for a systemcoupled with a heat reservoir was given based on the Feynman path-integral represen-tation of the transition probability, i.e. the diagonal part of a reduced density matrixof the system. The derived Langevin equations are of the form of the Lagrangianequations of motion. In this article the temporal change of the reduced density matrixas a whole, or more precisely of the Wigner phase-space distribution, is treated, andthe Langevin equations equivalent to those mentioned above but in the form of thecanonical equation of motion are derived in the second order perturbational approx-imation with respect to interactions between the system and the reservoir.
