General properties of nonlinear mean field Fokker-Planck equations
, 2007 Recently, several authors have tried to extend the usual concepts of thermodynamics and kinetic theory in order to deal with distributions that can be non-Boltzmannian. For dissipative systems described by the canonical ensemble, this leads to the notion

On a Fokker-Planck equation for wealth distribution
, 2018 We study here a Fokker-Planck equation with variable coefficient of diffusion and boundary conditions which appears in the study of the wealth distribution in a multi-agent society [ 2 , 10 , 22 ]. In particular, we analyze the large-time behavior of the

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

Onset of Fokker-Planck dynamics within a Closed Finite Spin System
, 2012 Relaxation according to Fokker-Planck equations is a standard scenario in classical statistical mechanics. It is however not obvious how such an equilibration may emerge within a closed, finite quantum system.

Fokker-Planck-Equation Approach to Flow Alignment in Liquid Crystals
, 1976 A nonlinear inhomogeneous relaxation equation for the alignment tensor is derived from a Fokker-Planck-equation for the orientational distribution function where torques exerted by a molecular field and by the gradient of the flow velocity are taken into

Binary spectral collocation method for the nonlinear Fokker-Planck equation
Journal of Algorithms & Computational TechnologyA mixed Laguerre-Legendre spectral collocation schemes is constructed for initial-boundary value problem of the nonlinear Fokker-Planck nonhomogeneous equations and the linear Fokker-Planck homogeneous equation by using the Laguerre interpolation ...

Stochastic analysis of surface roughness
, 2003 For the characterization of surface height profiles we present a new stochastic approach which is based on the theory of Markov processes. With this analysis we achieve a characterization of the complexity of the surface roughness by means of a Fokker ...

Global existence for the Vlasov–Euler–Fokker–Planck system in low-regularity space
Results in Applied MathematicsThis 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.
