Induced parity-odd effective action for a Dirac field on S² × S¹
We evaluate the parity-odd part of the effective action due to massive Dirac fermions on a S² × S¹ manifold, minimally coupled to an external Abelian gauge field. We do that for a special class of gauge-field configurations, which is especially suitable to the study of the behavior of the fermionic...

| Sumario: | We evaluate the parity-odd part of the effective action due to massive Dirac fermions on a S² × S¹ manifold, minimally coupled to an external Abelian gauge field. We do that for a special class of gauge-field configurations, which is especially suitable to the study of the behavior of the fermionic determinant under large gauge field configurations, which are allowed by the space-time geometry. |
