| Jan 30, 2021 at 14:54 | comment | added | Aleph12345 | Ok, perfect. And there exist some kind of "exterior covariant derivative" $\tilde{d}$ constructed with the connection $\nabla$? Or this has no use? | |
| Jan 30, 2021 at 1:50 | comment | added | Qmechanic♦ | Yes, if you mean the exterior derivative $\mathrm{d}$. | |
| Jan 30, 2021 at 1:49 | comment | added | Aleph12345 | Oh Thanks! And what about if the connection $\nabla$ is not TorsionFree? The correct definition should be with the partial derivative $\partial$ then? | |
