Abstract:
We present the stochastic solution to a generalized fractional partial differential equation (fPDE) involving a regularized operator related to the so-called Prabhakar operator and admitting as specific cases, among others, the fractional diffusion equation and the fractional telegraph equation. The stochastic solution is expressed as a Lévy process time-changed with the inverse process to a linear combination of (possibly subordinated) independent stable subordinators of different indices. Furthermore a related stochastic differential equation (SDE) is derived and discussed.
Keywords:
time-changed processes, Lévy processes, Prabhakar operators, regularized Prabhakar derivative, fractional derivatives, stochastic solution.
