Duality equivalence between nonlinear self-dual and topologically massive models

In this Letter we study the dual equivalence between the generalized self-dual (SD) and topologically massive (TM) models. To this end we linearize the model using an auxiliary field and apply a gauge embedding procedure to construct a gauge equivalent model. We clearly show that, under the above conditions, a nonlinear SD model always has a duality equivalent TM action. The general result obtained is then particularized for a number of examples, including the Born–Infeld–Chern–Simons (BICS) model recently discussed in the literature.
