For example, if B and B* are components of a plane wave, they satisfy the d’Alembert equations (123) and (124). However, in special relativity, the number Ã is a function of the spacetime coordinate xm .
From the terms (170) qL ¼ gGmn Â An ¼ ÀgAn Â Gmn qAm ð171Þ So the sum of terms (which appear on the left-hand side of the field equation) from variation in the term À14Gmn Gmn in the Lagrangian (167) is Dn Gmn qn Gmn þ gAn Â Gmn ð172Þ which is a covariant derivative in electrodynamics invariant under a local O(3) transformation.

The coefficient g in the vacuum field is k=Að0Þ and is e="h in the matter field. The process hk ! eAð0Þ " ð281Þ is therefore a transfer of photon linear momentum to an electron, as in the Compton effect. As soon as " h is introduced, Planck quantization is also introduced. Since e is a property of neither the electromagnetic field nor the Dirac electron, the equation hk ¼ eAð0Þ " ð282Þ can be regarded [47–61] as a Planck quantization of the factor g in the vacuum: g¼ k e ¼ " Að0Þ h ð283Þ The Lehnert equations are a great improvement over the Maxwell–Heaviside equations [45,49] but are unable to describe phenomena such as the Sagnac effect and interferometry , for which an O(3) internal gauge space symmetry is needed.
