Debye Potentials for Maxwell and Dirac Fields from a Generalisation of the Killing-Yano Equation
arXiv:gr-qc/9610037 · doi:10.1063/1.532140
Abstract
By using conformal Killing-Yano tensors, and their generalisations, we obtain scalar potentials for both the source-free Maxwell and massless Dirac equations. For each of these equations we construct, from conformal Killing-Yano tensors, symmetry operators that map any solution to another.
