Steady-State L\'evy Flights in a Confined Domain

, 2008
We derive the generalized Fokker-Planck equation associated with a Langevin equation driven by arbitrary additive white noise. We apply our result to study the distribution of symmetric and asymmetric L\'{e}vy flights in an infinitely deep potential well.

Diffusion Coefficients for Resonant Relativistic Wave‐Particle Interactions Using the PIRAN Code

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Quasilinear diffusion coefficients can be used to model the response of charged particles to resonant wave‐particle interactions. The calculation of these coefficients is sufficiently complicated and arduous to render it prohibitive to many potential users, because of the expense in time spent developing the code.

Subspace Approximations to the Focused Transport Equation of Energetic Particles, I. The Standard Form

The Open Journal of Astrophysics
The Fokker-Planck equation describing the transport of energetic particles interacting with turbulence is difficult to solve analytically. Numerical solutions are of course possible but they are not always useful for applications.

Keller–Segel type approximation for nonlocal Fokker–Planck equations in one-dimensional bounded domain

European Journal of Applied Mathematics
Numerous evolution equations with nonlocal convolution-type interactions have been proposed. In some cases, a convolution was imposed as the velocity in the advection term.

Medium‐Range Predictability of the Wintertime Bering Sea Ice Edge Using Linear Inverse Modeling

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Beginning in autumn, sea ice expands into the southern Bering Sea, where it remains until spring. In winter, some commercial stocks, particularly crabs, thrive in ice‐infested areas, necessitating short‐lead forecasts of the ice edge for fishers.

Generalized Fokker-Planck Equation for the Modified Landau-Lifshitz Equation with Poisson White Noise [PDF]

Журнал нано- та електронної фізики, 2013
Using the modified stochastic Landau-Lifshitz equation driven by Poisson white noise, we derive the generalized Fokker-Planck equation for the probability density function of the nanoparticle magnetic moment.

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 ...

The Fokker-Planck Equation [PDF]

, 2010
In 1984, H. Risken authored a book (H. Risken, The Fokker-Planck Equation: Methods of Solution, Applications, Springer-Verlag, Berlin, New York) discussing the Fokker-Planck equation for one variable, several variables, methods of solution and its applications, especially dealing with laser statistics.

Quantum transport equations for Bose systems taking into account nonlinear hydrodynamic processes

Condensed Matter Physics, 2014
sing the method of nonequilibrium statistical operator by Zubarev, an approach is proposed for the description of kinetics which takes into account the nonlinear hydrodynamic fluctuations for a quantum Bose system. Non-equilibrium statistical operator is
