Quantum-kinetic equations for time correlation functions in higher-order perturbation theory

The memory kernel of the kinetic equation for the time correlation function of a quantum fluid is determined both in third order of the interaction strength and in the low-density approximation. The results are obtained with the help of a diagram representation for the kernel. The connexion with the kinetic theory for classical fluids is established.
