Stochastic Solution of Fractional Fokker-Planck Equations with Space-Time-Dependent Coefficients

This paper develops solutions of fractional Fokker-Planck equations describing subdiffusion of probability densities of stochastic dynamical systems driven by non-Gaussian Lévy processes, with space-time-dependent drift, diffusion and jump coefficients, thus significantly extends Magdziarz and Zorawik's result in "M. Magdziarz and T. Zorawik, Stochastic representation of fractional subdiffusion equation. The case of infinitely divisible waiting times, Lévy noise and space-time-dependent coefficients. Proc. Amer. Math. Soc., Accepted (2015)." Fractional Fokker-Planck equation describing subdiffusion is solved by our result in full generality from perspective of stochastic representation.
