WebNote that the first evolution is always Markovian, i.e., the corresponding dynamical map is CP-divisible, as the hazard rate h (t) is always positive. On the contrary, the quantity μ (t) in the latter local master equation can typically become negative, which results in a non-Markovian dynamics.
