WebThe numerical solutions to a non-linear Fractional Fokker–Planck (FFP) equation are studied estimating the generalized diffusion coefficients. The aim is to model anomalous diffusion using an FFP description with fractional velocity derivatives and Langevin dynamics where Lévy fluctuations are introduced to model the effect of non-local transport due to … Web10 de abr. de 2024 · A weak solution (X, B) can be loosely described as a pair consisting of the stochastic process X and the Brownian motion B satisfying the ISDE. A strong solution is a weak solution (X, B) such that X is a function of the Brownian motion B and the initial starting point x. (See Refs. 11 11. N.
