Overview on the anomaly and Schwinger term in two dimensional QED Adam, C; Bertlmann, R A; Hofer, P 72 PHYSICS OF ELEMENTARY PARTICLES AND FIELDS; QUANTUM ELECTRODYNAMICS; TWO-DIMENSIONAL CALCULATIONS; DISPERSION RELATIONS; PERTURBATION THEORY; SCHWINGER TERMS; VACUUM STATES; 662220 The axial anomaly of two-dimensional QED is computed in different ways (perturbative, via dispersion integrals, path integral and index theorem) and their relation is discussed as well as the relation between anomaly, Schwinger term and the Dirac vacuum. Some features of the special case of massless fermions (Schwinger model) and some methods of exactly solving it are demonstrated. (authors). Vienna Univ. (Austria).
