%0 Journal Article %T SL(2,Z) duality of Born-Infeld theory from self-dual electrodynamics in 6 dimensions %A D. S. Berman %J Physics %D 1997 %I arXiv %R 10.1016/S0370-2693(97)00919-2 %X We reformulate the Born-Infeld action, coupled to an axion and a dilaton in a duality manifest way. This action is the generalization of the Schwarz-Sen action for non-linear electrodynamics. We show that this action may be obtained by dimensional reduction on a torus of a self-dual theory in 6 dimensions. The dilaton-axion being identified with the complex structure of the torus. Applications to M-theory and the self-dual IIB three brane are investigated. %U http://arxiv.org/abs/hep-th/9706208v2
