“…For that purpose we start introducing the densities of particles n (r) and of energy ĥ (r). As described elsewhere, 10 reiterated application of the law of Eq. ͑4͒ requires that, for the closure condition to be satisfied, we must introduce as basic dynamical variables the fluxes of all order of both densities, Î n [r] (r) and Î h [r] (r), with rϭ1,2,3, .…”
