The infra-red limit of a planar static D3-brane in AdS5 S5 is a tensionless D3-brane at the anti-de Sitter horizon with dynamics governed by a strongfield limit of the DiracBornInfeld action, analogous to that found from the BornInfeld action by Bialynicki-Birula. As in that case, the field equations are those of an interacting 4D conformal invariant field theory with an Sl(2;R) electromagnetic duality invariance, but the D3-brane origin makes these properties manifest. We also find an Sl(2;R)-invariant action for these equations.
