We study the equivalence between the B∧ F self-dual (SD B∧ F ) and the B∧ F topologically massive (TM B∧ F ) models including the coupling to dynamical, U(1) charged fermionic matter. This is done through an iterative procedure of gauge embedding that produces the dual mapping. In the interactive cases, the minimal coupling adopted for both vector and tensor fields in the self-dual representation is transformed into a non-minimal magnetic like coupling in the topologically massive representation but with the currents swapped. It is known that to establish this equivalence a current–current interaction term is needed to render the matter sector unchanged. We show that both terms arise naturally from the embedding procedure.
