Symmetry of polarization space and supplementary invariance of Maxwell's equations
Abstract
The invariance of the twopotential formulation of Maxwell's equations relative to a set of transformations of the fields and potentials forming the group GL(2, c) ⊗ GL(2, c), which narrows to the group GL(2, c) when the number of independent degrees of freedom characteristic of an electromagnetic field is taken into account, is established. The indicated invariance reflects a symmetry which is internally intrinsic to the polarization space of an electromagnetic field.
