Poincaré dual of D=4, N=2 supergravity with tensor multiplets

We study, in an arbitrary even number D of dimensions, the duality between massive D/2 tensors coupled to vectors, with masses given by an arbitrary number of “electric” and “magnetic” charges, and (D/2−1) massive tensors. We develop a formalism to dualize the Lagrangian of D=4, N=2 supergravity coupled to tensor and vector multiplets, and show that, after the dualization, it is equivalent to a standard D=4, N=2 gauged supergravity in which the special geometry quantities have been acted on by a suitable symplectic rotation.
