ABSTRACT
The perturbed electron propagator is discussed as a means of obtaining static linear response properties. The dynamic self-energy is derived at first order in the field and second order in correlation using a diagrammatic method. We discuss the invariance properties of the first-order perturbed electron density which may be obtained from the perturbed electron propagator formalism. © 1995 American Institute of Physics.
