Recently it has been speculated that the $S$-matrix elements on the world volume of ${D}_{3}$-branes should satisfy the Ward identity corresponding to the $S$-duality transformations. For a single brane and in the low energy limit, this indicates that in the Abelian Dirac-Born-Infeld and Chern-Simons actions, the combination of contact terms …
