For the SL(2,R) duality-invariant generalization of Maxwell electrodynamics in the presence of both electric and magnetic sources, we formulate a local, manifestly duality-symmetric, Zwanziger-type action by introducing a pair of four-potentials A(mu) and B-mu in a judicious way. On the two potentials A(mu) and B-mu the SL(2,R) duality transformation acts in a simple linear manner. In quantum theory including charged source fields, this action can be recast as a SL(2,Z)-invariant action. Also given is a Zwanziger-type action for SL(2,R) duality-invariant Born-Infeld electrodynamics which can be important for D-brane dynamics in string theory. (C) 2013 Elsevier Inc.
