| Abstract: | The projector formalism of Zwanzig-Mori type is extended to obtain generalized Fokker-Planck and generalized nonlinear Langevin equations for coarse-grained variables when the underlying microscopic dynamics is dissipative and noisy (stochastic). |
| Keywords: | Brownian motion theory projector formalism Fokker-Planck equation nonlinear Langevin equation |
