Until now, we have been concerned mainly with the perturbative aspects of QCD. For these, the use of either a canonical or path integral formulation of field theory is largely a matter of taste. Nonperturbative aspects of QCD, however, can be formulated with greater clarity in a functional language. In this section, we briefly review the Feynman path integral formalism, in particular as applied to field theory. Of course, this is no substitute for a detailed treatment, for which the interested reader may consult the lectures of Fadeyev (1976) and Lee (1976) or the textbooks of Itzykson and Zuber (1980) and Fadeyev and Slavnov (1980).
