Rough nonlocal diffusions [PDF]

open access: yes, 2019
We consider a nonlinear Fokker-Planck equation driven by a deterministic rough path which describes the conditional probability of a McKean-Vlasov diffusion with "common" noise.

The Schauder estimate in kinetic theory with application to a toy nonlinear model [PDF]

open access: yes, 2020
This article is concerned with the Schauder estimate for linear kinetic Fokker-Planck equations with H\"older continuous coefficients. This equation has an hypoelliptic structure.

Numerical solution for the time-fractional Fokker–Planck equation via shifted Chebyshev polynomials of the fourth kind

open access: yesAdvances in Difference Equations, 2020
This paper provides a numerical approach for solving the time-fractional Fokker–Planck equation (FFPE). The authors use the shifted Chebyshev collocation method and the finite difference method (FDM) to present the fractional Fokker–Planck equation into ...

Radiative Transfer Limits of Two-Frequency Wigner Distribution for Random Parabolic Waves [PDF]

open access: yes, 2006
The present note establishes the self-averaging, radiative transfer limit for the two-frequency Wigner distribution for classical waves in random media. Depending on the ratio of the wavelength to the correlation length the limiting equation is either a ...

Interval Wavelet Numerical Method on Fokker-Planck Equations for Nonlinear Random System

open access: yesAdvances in Mathematical Physics, 2013
The Fokker-Planck-Kolmogorov (FPK) equation governs the probability density function (p.d.f.) of the dynamic response of a particular class of linear or nonlinear system to random excitation.

Entropy Production Associated with Aggregation into Granules in a Subdiffusive Environment

open access: yesEntropy, 2018
We study the entropy production that is associated with the growing or shrinking of a small granule in, for instance, a colloidal suspension or in an aggregating polymer chain. A granule will fluctuate in size when the energy of binding is comparable to

Mean-field approximation of counting processes from a differential equation perspective

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
Deterministic limit of a class of continuous time Markov chains is considered based purely on differential equation techniques. Starting from the linear system of master equations, ordinary differential equations for the moments and a partial ...

Derivation of the Fractional Fokker–Planck Equation for Stable Lévy with Financial Applications

open access: yesMathematics, 2023
This paper aims to propose a generalized fractional Fokker–Planck equation based on a stable Lévy stochastic process. To develop the general fractional equation, we will use the Lévy process rather than the Brownian motion.

Self-Consistency of the Fokker-Planck Equation

open access: yesCoRR, 2022
The Fokker-Planck equation (FPE) is the partial differential equation that governs the density evolution of the Itô process and is of great importance to the literature of statistical physics and machine learning. The FPE can be regarded as a continuity equation where the change of the density is completely determined by a time varying velocity field ...

A fractional model to describe the Brownian motion of particles and its analytical solution

open access: yesAdvances in Mechanical Engineering, 2015
In this article, we apply a relatively modified analytic iterative method for solving a time-fractional Fokker–Planck equation subject to given constraints.
