N2  - Two equations for the macroscopic part W of the statistical operator are considered:
1. the master equation W = — MW, t
2. the exact equation W = — J K(t — r) W (r) dr. 
It follows from the physical equivalence of the solutions together with a stability assumption and the assumption that there is a time τ* after which also the derivatives of the solutions are equivalent, that τ* is the life-time of the kernel K and that  Conversely, the equivalence of the solutions follows from assumptions on the life-time of the kernel K together with a stability assumption and a smoothness assumption on the initial statistical operator W(0).
