field the same equation is satisfied by the average of the integer powers of the density, which are the moments of the … related probability density. For a generic vector field the Fokker–Planck equation for the moments is slightly modified. We … probabilistic meaning of the moments is discussed and the comparison between the analytical results and the numerical simulation is …

For a general class of collision operators, we perform an asymptotic analysis of the moments of the stationary … separable kernels, which are also known as “relaxation time approximations”. It turns out that the behaviour of the moments is …
