Phys. Rev. D 35, 1268–1279 (1987)Gauge and gravitational anomalies in two dimensionsReceived 22 September 1986; published in the issue dated 15 February 1987 Gauge and gravitational anomalies are studied in two dimensions. In the gauge-anomaly case, we obtain the solution of the anomaly equation (the Wess-Zumino term) with only gauge fields, without auxiliary fields. Then we show, up to the second nontrivial order, that this solution agrees with the explicit Feynman-diagram calculation. In the gravitational-anomaly case we show, up to the second nontrivial order, that the anomaly obtained by the differential geometric method agrees with the explicit Feynman-diagram calculation. © 1987 The American Physical Society URL:
