Footnote: Delete the 2nd sentence. At the end, add the following paragraph. “In a more general mathematical sense, the gauge covariant derivative of QFT and the covariant derivative of GR, are birds of a feather. Each entails a local variation in the four-derivative, due to a field - the gauge field for QFT and the spacetime metric field for GR.” |
