Abstract: Electron propagator theory (EPT) provides one- or two-electron propagators based on the Dyson equation. These propagator have been applied to predictively evaluation of electron binding or excitation energies of atoms and molecules in quantum chemistry. Although propagators have been used in solid-state physics, few texts have considered fields of chemistry. We illustrate the EPT by from basic concept of Green's function to a construction of second-order one-electron propagator. So we concentrate on principles and equations rather than on numerical results and recent developments of the electron propagator. This goal could be achieved if the present paper is useful in constructing new propagators.
