  • $\begingroup$ Won't that sum over cyclic KLM create a bunch of pairs of $T_{ab}$ + $T_{ba}$? $\endgroup$

  • $\begingroup$ @Jerry Schirmer what do you mean with $T_{ab}$ -- the torsion tensor has 3 indices. So $T_{ab}$ is the energy-momentum tensor ? $\endgroup$

  • $\begingroup$ Sorry, I typoed out the upper index. Irrespecitvely, you're symmetrizing over anti-symmetric indices. $\endgroup$
