@pellis , in the (second)last line of the proof, why did you drop the partial mu of S(Λ) term ? Is it zero for some reason ? I am talking about the line before "Thus".

I have read that we can define covariant derivative for spinors using the spin connection. But I can't see its proof in any textbook. Can anyone point to a reference where it is proved that such a definition indeed transforms covariantly ?

Thanks for the reply. I just added some more details to the question. Since I was having trouble with use Latex here, I posted a question on Physics Stack Exchange : https://physics.stackexchange.com/questions/816112/prove-that-levi-civita-tensor-density-is-invariant Hopefully that will be helpful.

This is a problem from the textbook Supergravity ( by Daniel Z. Freedman and Antoine Van Proeyen ). I am trying to learn general relativity from this book. I am attempting to do the later part of the Exercise 7.14 ( on page 148 ). Basically it asks us to explicitly show that the Levi-Civita...
