Abstract
In this paper, we review the construction of the adiabatic expansion for Bose and Fermi systems and show how it may be used to explore the chiral and parity anomalies for Dirac fermions without the need to compute Feynman diagrams. One interesting application examines how the simple spectral-flow picture of the chiral anomaly is modified by the inclusion of a fermion mass.
