| 1 | Some time ago the authors proposed a new approach to self-dual electrodynamics and its superextensions, based on introducing auxiliary (super)fields which ensure linearization of the duality transformations. In the talk this universal method is applied for analysis of the self-duality properties of the N = 2 Born-Infeld (BI) action with the nonlinearly realized “hidden” N = 4 supersymmetry. Its self-duality is proved up to the 10th order in the superfield strengths. The conjecture about the general structure of the N = 2 BI action modified by the auxiliary chiral superfields is put forward. Keywords: supersymmetry, duality, superfield | 1494 | ||||
