    "abstract": "An original method to exactly solve the non-Markovian Master Equation\ndescribing the interaction of a single harmonic oscillator with a quantum\nenvironment in the weak coupling limit is reported. By using a superoperatorial\napproach we succeed in deriving the operatorial solution for the density matrix\nof the system. Our method is independent of the physical properties of the\nenvironment. We show the usefulness of our solution deriving explicit\nexpressions for the dissipative time evolution of some observables of physical\ninterest for the system, such as, for example, its mean energy.",
