Residual gauge symmetry in light-cone electromagnetism
Abstract We analyze the residual gauge freedom in light-cone electromagnetism in four dimensions. The standard boundary conditions involved in the so-called lc 2 formalism, which contains only the two physical degrees of freedom, allow for a subset of residual gauge transformations. We relax the bou...
