  • Forward and reverse equations and boundary conditions. Our second example is that of the Ornstein-Uhlenbeck process, described by ∂tP = ∂x(βxP​)+ D In terms of joint probability densities, detailed balance may be stated as follows.

    A standard scalar Wiener process is generated by the stochastic differential equation. Bibcode : PhRv. Furthermore, in the case of overdamped dynamics when the Fokker—Planck equation contains second partial derivatives with respect to all variables, the equation can be written in the form of a master equation that can easily be solved numerically [11].

    the Ornstein–Uhlenbeck process and the spectral properties of the problem for the Fokker–Planck (backward Kolmogorov) equation that we derived . The detailed balance condition () results in the stationary Fokker–Planck equa. The Ornstein-Uhlenbeck process is a Gaussian process with m(t) = 0, C(t, s) = λe​−α|t−s| with The backward Kolmogorov equation is the heat equation.

    While the Fokker—Planck equation is used with problems where the initial distribution is known, if the problem is to know the distribution at previous times, the Feynman—Kac formula can be used, which is a consequence of the Kolmogorov backward equation.

    In more abstract language, this is a balance equation of the form. P[Xn+1 < z. as the variable, this is sometimes called the backward equation or backward method. and variance coefficient a(x) = 1, the forward equation for Brownian motion is just the Example: The Ornstein-Uhlenbeck process with coefficients a(x) = σ2 and b​(x) = −γx stationary distributions satisfy a detailed-balance condition. Namely.
    Furthermore, in the case of overdamped dynamics when the Fokker—Planck equation contains second partial derivatives with respect to all variables, the equation can be written in the form of a master equation that can easily be solved numerically [11].

    While the Fokker—Planck equation is used with problems where the initial distribution is known, if the problem is to know the distribution at previous times, the Feynman—Kac formula can be used, which is a consequence of the Kolmogorov backward equation. The equation can be generalized to other observables as well.
