Abstract
A detailed discussion of the relationships following from time reversa l invariance or covariance of many-body theories is given. The discuss ion includes equilibrium and non-equilibrium Keldysh Green functions. It is shown that self-consistent RPA approximations conserve the above deduced relationships.
