Description

The effective gauge field action due to fermions coupled to SU(N) gauge fields in three dimensions is found to change by +- πVertical BarnVertical Bar under a homotopically nontrivial gauge transformation with winding number n. This gauge noninvariance can be eliminated by adding a parity-violating topological term to the action, or by regulating the theory in a way which produces this term automatically in the effective action. The Euler-Heisenberg effective action is calculated in the SU(2) theory and in QED
