    "abstract": "The non-Markovian behaviour of open quantum systems interacting with a\nreservoir can often be described in terms of a time-local master equation\ninvolving a time-dependent generator which is not in Lindblad form. A\nsystematic perturbation expansion of the generator is obtained either by means\nof van Kampen\u0027s method of ordered cumulants or else by use of the\nFeynman-Vernon influence functional technique. Both expansions are demonstrated\nto yield equivalent expressions for the generator in all orders of the\nsystem-reservor coupling. Explicit formulae are derived for the second and the\nfourth order generator in terms of the influence functional.",
