Chapter 4 presented a thorough investigation of the anomaly within perturbation theory. This chapter presents the nonperturbative view. Section 5.1 performs a chiral transformation of the path integral and finds the anomalous Ward identity. Section 5.2 regularizes the transformation Jacobian à la Fujikawa, and in this way derives the singlet anomaly; the two-dimensional case is added in Section 5.3. Section 5.4 shows the regularization independence of the anomaly and Section 5.5 discusses the conflict between gauge- and chiral symmetry in the light of an uncertainty principle. Section 5.6 demonstrates the generalization of the path integral method to non-Abelian fields leading to non-Abelian anomaly. Finally, Section 5.7 carries out the regularization of the Jacobian by means of the heat kernel method and by the zeta function procedure.

Keywords:   path integrals, Ward identity, Jacobian, gauge symmetry, chiral symmetry, non-Abelian anomaly, heat kernel method, zeta function
