Low-dimensional spike rate models derived from networks of adaptive integrate-and-fire neurons: Comparison and implementation.

PLoS Computational Biology, 2017
The spiking activity of single neurons can be well described by a nonlinear integrate-and-fire model that includes somatic adaptation. When exposed to fluctuating inputs sparsely coupled populations of these model neurons exhibit stochastic collective ...

Wealth distribution in presence of debts. A Fokker--Planck description

, 2017
We consider here a Fokker--Planck equation with variable coefficient of diffusion which appears in the modeling of the wealth distribution in a multi-agent society. At difference with previous studies, to describe a society in which agents can have debts,

Patient treatment prediction by continuous time random walk inside complex system

MATEC Web of Conferences, 2018
Stochastic resonance model for medical patient condition is proposed. Approach has been generalized by means of fractional Fokker-Planck equation and subdiffusion processes.

Closure of the single fluid magnetohydrodynamic equations in presence of electron cyclotron current drive

EPJ Web of Conferences, 2015
In the presence of electron cyclotron current drive (ECCD), the Ohm’s law of single fluid magnetohydrodynamics (MHD) is modified as E + v × B = η(J – JECCD).

Large-time behavior in non-symmetric Fokker-Planck equations

, 2015
We consider three classes of linear non-symmetric Fokker-Planck equations having a unique steady state and establish exponential convergence of solutions towards the steady state with explicit (estimates of) decay rates.

Generalised symmetries of remarkable (1+2)-dimensional Fokker–Planck equation

European Journal of Applied Mathematics
Using an original method, we find the algebra of generalised symmetries of a remarkable (1+2)-dimensional ultraparabolic Fokker–Planck equation, which is also called the Kolmogorov equation and is singled out within the entire class of ultraparabolic ...

Nonlinear Fokker-Planck Equation in the Model of Asset Returns

Symmetry, Integrability and Geometry: Methods and Applications, 2008
The Fokker-Planck equation with diffusion coefficient quadratic in space variable, linear drift coefficient, and nonlocal nonlinearity term is considered in the framework of a model of analysis of asset returns at financial markets.
