Abstract

We calculate the exact parity odd part of the effective action (Γodd2d+1\Gamma_{odd}^{2d+1}) for massive Dirac fermions in 2d+1 dimensions at finite temperature, for a certain class of gauge field configurations. We consider first Abelian external gauge fields, and then we deal with the case of a non-Abelian gauge group containing an Abelian U(1) subgroup. For both cases, it is possible to show that the result depends on topological invariants of the gauge field configurations, and that the gauge transformation properties of Γodd2d+1\Gamma_{odd}^{2d+1} depend only on those invariants and on the winding number of the gauge transformation.
