Feb 2, 2020 at 14:58 comment added Noone The absence of that extra term would mean that there are no interactions between gluons.
Feb 2, 2020 at 14:51 comment added Solidification That does not require you to know the commutator. Does it?
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?
