Fractional derivative in continuous-time Markov processes and applications to epidemics in networks by Matteo D'Alessandro, Piet Van Mieghem

“…Continuous-time Markov processes are governed by the Chapman-Kolmogorov differential equation. We show that replacing the standard time derivative of the governing equation with a Caputo fractional derivative of order 0<α<1, leads to a fractional differential equation whose solution can describe the state probabilities of a class of non-Markovian stochastic processes. …”
