The spectral representation of many-time Green's functions is generalized to Green's functions in which several operators may appear in normal order. The Heisenberg picture matrix elements are given for the Green's function having one external interaction line and one external quasi-particle line an
## Abstract We present a method for calculating the oneβparticle Green's function for molecules. The scheme is essentially that proposed by Schneider and Taylor [1]. The Green's function is obtained through the Dyson equation. Closed expressions result by using the functional derivation technique t
