    "abstract": "In phenomenological applications the time evolution of subsystems immersed in\nan external environment are sometimes described by Markovian semigroups of\nRedfield type that result non-positive: the appearence of negative\nprobabilities is avoided by restricting the admissible initial conditions to\nthose states that remain positive under the action of the dynamics. We show\nthat this often adopted procedure may lead to physical inconsistencies in\npresence of entanglement.",
