Minimal spin connection, and the standard content of GR
In Sec. 12.1 of 'Superstring Theory', by Green, Schwarz, and Witten, the minimal spin connection is motivated as follows:
If we are to avoid modifying the standard content of general
relativity, …

Decomposition of the torsion tensor
See Update below.
Consider the torsion tensor $T_{\mu\nu\rho} = -T_{\mu\rho\nu}$. In a local Lorentz frame, as determined by a vierbein $e^{a}{}_{\mu}$, it may equivalently be given as $T_{abc} = e^{ …
