Abstract: The paper presents a generalized Fokker-Planck equation for the probability density P(x,t) of the internal parameter x, when the external control parameter y is affected by fluctuations. The treatment is generally valid for all transition phenomena (either pumped or at thermal equilibrium), whenever they are described by a mean field. As an example, the nonlinear diffusion equation for the optical bistability is derived using the general Fokker-Planck equation and heuristic arguments.
