    • As shown in P. Pechukas, Phys. Rev. Lett. 73, 1060 (1994), reduced dynamics in general need not be completely positive (not even positive) on the whole system space. In the case of weak coupling between system and environment, short memory of the environment and time coarse graining, the description of the reduced dynamics by a completely positive map is justified even in the case of initial entanglement [see
