Communications and Control Engineeringternal fields as perturbations. We believe that this approach is both fundamental and easy to understand; for this reason it will be given a rather general formulation which pretends both to survey the elementary literature, and to place each individual property in its proper context.

Pair Functions and Diagrammatic Perturbation Theory,ason for such an approach is that, while some of the methods which we shall discuss correspond to variational wavefunctions, the majority must be viewed as non-variational. Hence, perturbation methods provide a common approach to the discussion of both types of theory.
