Derivative expansions of fermion determinants: anomaly-induced vertices, Goldstone-Wilczek currents, and Skyrme terms

An algebraic procedure for evaluating functional determinants in powers of derivatives of external fields is used to calculate one-fermion-loop contributions to low-energy effective Lagrangians involving anomaly-induced vertices, Goldstone-Wilczek currents, and Skyrme terms.
