چکیده

We consider a Fokker-Planck equation in a general domain in R with Lploc drift term and W 1,p loc diffusion term for any p > n. By deriving an integral identity, we give several measure estimates of regular stationary measures in an exterior domain with respect to diffusion and Lyapunov-like or anti-Lyapunov-like functions. These estimates will be useful to problems such as the existence and non-existence of stationary measures in a general domain as well as the concentration and limit behaviors of stationary measures as diffusion vanishes.

A note on the Markov property of stochastic processes described by nonlinear FokkerヨPlanck equations

We study the Markov property of processes described by generalized Fokker–Planck equations that are nonlinear with respect to probability densities such as mean ,eld Fokker–Planck equations and Fokker–Planck equations related to generalized thermostatistics. We show that their transient solutions describe non-Markov processes. In contrast, stationary solutions can describe Markov processes. As ...

Uniqueness of degenerate Fokker – Planck equations with weakly differentiable drift whose gradient is given by a singular integral ∗

In this paper we prove the uniqueness of solutions to degenerate Fokker–Planck equations with bounded coefficients, under the additional assumptions that the diffusion coefficient has W 1,2 loc regularity, while the gradient of the drift coefficient is merely given by a singular integral.

Steady States of Fokker-planck Equations: Iii. Degenerate Diffusion

This is the third paper in a series concerning the study of steady states of a Fokker-Planck equation in a general domain in R with Lp̄loc drift term and W 1,p̄ loc diffusion term for any p̄ > n. In this paper, we give some existence results of stationary measures of the Fokker-Planck equation under Lyapunov conditions which allow the degeneracy of diffusion.
