We find general non-linear Lagrangians invariant under the electric-magnetic duality. They are characterized by an arbitrary function and are reduced to the Maxwell theory in weak field limit. We present some explicit examples that include generalizations of the Born-Infeld theory. (C) 1999 Elsevier Science B.V. All rights reserved.
