Feb 2, 2020 at 14:40 | comment | added | Noone | $G^{j}_{μν}$ has an extra term. The mathematical reason for that extra term is that $SU(N)$ is a non abelian group and the physical reason is that gluons "carry" color charge and interact with its other while a photon does not "carry" any charge and does not interact with other photons. | |
Feb 2, 2020 at 14:07 | comment | added | Solidification | How does that follow from the commutator relations? | |
