Analyzing and forecasting the dynamics of Internet resource user sentiments based on the Fokker–Planck equation

open access: yesРоссийский технологический журнал
Objectives. The study aims to theoretically derive the power law observed in practice for the distribution of characteristics of sociodynamic processes from the stationary Fokker–Planck equation and apply the non-stationary Fokker–Planck equation to ...

Solving procedure for a twenty-five diagonal coefficient matrix: direct numerical solutions of the three dimensional linear Fokker-Planck equation

open access: yes, 2005
We describe an implicit procedure for solving linear equation systems resulting from the discretization of the three dimensional (seven variables) linear Fokker-Planck equation. The discretization of the Fokker-Planck equation is performed using a twenty-

Periodic long-time behaviour for an approximate model of nematic polymers

open access: yes, 2011
We study the long-time behaviour of a nonlinear Fokker-Planck equation, which models the evolution of rigid polymers in a given flow, after a closure approximation.

About Fokker-Planck equation with measurable coefficients and applications to the fast diffusion equation [PDF]

open access: yes, 2012
The object of this paper is the uniqueness for a $d$-dimensional Fokker-Planck type equation with non-homogeneous (possibly degenerated) measurable not necessarily bounded coefficients. We provide an application to the probabilistic representation of the

Global existence for the Vlasov–Euler–Fokker–Planck system in low-regularity space

open access: yesResults in Applied Mathematics
This paper investigates the global well-posedness of the Cauchy problem for the Vlasov–Fokker–Planck equation coupled with the incompressible Euler system around a normalized global Maxwellian in a periodic spatial domain.
