In this section the equations of motion (in real time) for the non-equilibrium
GREEN's functions are introduced. There are two different, but equivalent,
formulations: the KADANOFF-BAYM and the KELDYSH formulation. These
are treated in the following subsections. Finally, kinetic
equations under steady-state condition are presented.
