...on the gauge-invariance of classical electrodynamics ?(adsbygoogle = window.adsbygoogle || []).push({});

I'm thinking of flat Minkowski space-time of SR in which a charged particle moves and generates an electromagnetic field described by the well-known Lie/nard - Wiechert potential.

In this situation can we say all spacetime is homogenous ? If so, then can we infer that the gauge freedom of the L-W potential is disturbed, meaning that the gauge-parameter is necessarily 0 ?

If you think the questions and the whole subject of this post are idiotic, then the same label can be ascribed to the articlephys:0609152available at www.arxiv.org.

Daniel.

P.S. I share your feeling: WTF ? :surprised
