Subject: Fwd: 96(2) : On the placement of indices in the base manifold
Date: Sat, 6 Oct 2007 09:39:21 EDT
Dear prof Evans,
I have red note 2 to article 96 and I think that the Eq. 10 should be thread as:
If we start from
(D / F^a) = (R^a_b / q^b)
we will multiple it by tetrad q^lambda_a
q^lambda_a q^a_kappa (D / F^kappa) = q^lambda_a q^a_kappa (R^kappa_b / q^b)
there shouldn’t be three same indices in one statement so
delta^lambda_kappa (D / F^kappa) = delta^lambda_kappa (R^kappa_b / q^b)
(D / F^lambda) = (R^labda_b / q^b)
I think that this is more direct.
Also Eq. 25 make me no seance because this is not possible make such operation with indices.
The main result, Eq. 26, is of course alright.
Best Regards
Karel

OK many thanks, we can go with your method, and thanks for this coridal and professional refereeing!
