Abstract

Abstract Quantum relations between a class of boson Langevin equations and the associated Fokker-Planck equations are derived. The Fokker-Planck equations for the Wigner distribution Φ sym related with symmetric ordering of the boson operators, the distribution Φ A related with antinormal ordering, and the distribution Φ N related with normal ordering (P-representation) are given.
