Abstract

In this chapter, we shall see how the combined covariant-evolution-QED approach developed in the previous chapters can be implemented numerically. In principle, this is equivalent to solving the complete Bethe–Salpeter equation perturbatively, but in practice, of course, approximations have to be made. We shall consistently work in the Coulomb gauge.
