Abstract

This chapter converts the Dyson equation for the contour single-particle Green’s function to real-time variables. The corresponding equations for the Matsubara, right Keldysh, left Keldysh, lesser, greater, retarded, advanced, and Keldysh components are explicitly considered. A connection is also established with the original Kadanoff–Baym equations.
