Note that the time argument in the PDF P ( x , t ∣ ∣ x 0 ) is a vector of times: t = { t i } i = − − M M , and t ′ ( i ) = { t c } c = − − M , c ≠ ≠ i M . Adding all the coordinates and performing the integration in the order of faster times first (the order is determined randomly from a uniform distribution in the space of configurations) gives the full equation of motion in anomalous files of independent particles (averaging of the equation over all configurations is therefore further required). Indeed, even Eq. (9) is very complicated, and averaging further complicates things.
