Notes:
This paper outlines a program for the systematic treatment of correlation effects within density functional approaches to many-electron systems. This strategy is motivated by the observation that the ground state energy of an inhomogeneous electron gas is a functional of the many-body Hartree electron density. This fact is proved, and it is outlined how the functional can be constructed at any order of perturbation theory. Second order correlation contributions to the energy are discussed as an explicit example.
