| Mar 10, 2021 at 10:45 | comment | added | Jorge Casajus | I got it from Hobson's General Realativity: An introduction for physicists. It's equation 3.11, and this is exercise 3.8, which also requires to prove that equation yourself (something I thought I had done right) | |
| Mar 10, 2021 at 10:40 | comment | added | Eletie | Just to check, do you have a source for your first equation? Usually one writes $\Gamma = \{ \} + K$, with K being the contorsion tensor defined here en.wikipedia.org/wiki/Contorsion_tensor this slightly differs from your definitions. | |
| Mar 10, 2021 at 10:29 | comment | added | Jorge Casajus | And... Should I do that multiplying by the covariant or contravariant components of the metric tensor? If so, would't they still cancel out since the symmetries in the metric tensor won't induce any extra sign changes? | |
| Mar 10, 2021 at 10:24 | comment | added | Eletie | Yes your hunch is right: the symmetry properties only apply for the specific index combination, so its just a case of manipulating the indices to match the desired form. | |
