On Duality Rotations in Light-Like Noncommutative Electromagnetism
arXiv:hep-th/0103150 · doi:10.1142/S0217732301003231
Abstract
We study electric-magnetic duality rotations for noncommutative electromagnetism (NCEM). We express NCEM as a nonlinear commutative U(1) gauge theory and show that it is self-dual when the noncommutativity parameter θis light-like (e.g. θ^{0i}=θ^{1i}). This implies, in the slowly varying field approximation, self-duality of NCEM to all orders in θ.
