I'm curious to know whether anyone with good maths has anything to say about Dr Philip Gibbs' covariant formula for conserved currents of energy, momentum and angular- momentum derived from a general form of Noether’s theorem? I'm not a pro mathematician, but it(adsbygoogle = window.adsbygoogle || []).push({}); looksrelatively robust to me... I asked this before, but the post didn't seem to 'take'. Apologies if this is double posting - Bob edit - link. https://arxiv.org/pdf/gr-qc/9701028.pdf
