| Jan 31 at 20:33 | comment | added | ACuriousMind♦ | The curvature does not change if $G=\mathrm{U}(1)$, since the adjoint of Abelian groups is trivial and the relation between the electromagnetic fields and the curvature tensor is an elementary part of the covariant formulation of electromagnetism, and is given explicitly e.g. on Wikipedia. What sources are you using that teach you about "curvature 2-forms" in gauge theory but not about their basic relations to observable physics? | |
