Abstract

In Part I, we have considered some standard methods for many-body calculations on atomic systems. These methods are well developed and can treat certain electron-correlation effects to essentially all orders of perturbation theory. In Part II, we have considered three different methods for numerical QED calculations on bound systems, which have been successfully applied to various problems. All these methods are, however, in practice limited to one- and two-photon exchange, implying that electron correlation can only be treated in quite a restricted way. For many systems the electron correlation is of great importance, and to evaluate the QED effects accurately, it may be necessary to take into account also the combination of QED and correlational effects, which has not been done previously.
