摘要：

The effective action approach to Kohn-Sham density-functional theory provides a rigorous basis for carrying out systematic, first-principles calculations of the ground and excited state properties. In this work we apply the effective action formalism for developing the exact density-functional formulation of one-electron propagators. In particular, expressions for the exact Green's function and the self-energy operator are obtained entirely in terms of Kohn-Sham derived quantities.
