Axial anomalies in higher dimensions by dimensional continuation

Klein-Kaluza theories take a higher-dimensional perspective of four-dimensional constructions. The authors have used dimensional continuation in order to extract the 'axial anomalies' in such higher-dimensional theories-consistency conditions on the fermion content then arise by imposing a vanishing anomaly. These axial anomalies should rightfully emerge from consideration of the higher-dimensional gravitational contributions to it.
