Homework Help: (n,m) to (n+1,m) derivatives in Wald

  1. Dec 4, 2011 #1
    Could someone please explain the partial and covariant derivatives with upstairs index that appears all of a sudden in Wald in section 4.2 with no explanation? I haven't seen it anywhere else.

    1. The problem statement, all variables and given/known data

    (n,m)→(n+1,m) derivatives

    2. Relevant equations

    section 4.2--when the stress tensor is introduced, with downstairs indexes

    3. The attempt at a solution

    it was mentioned earlier by Wald; just didn't see it

    Can you perhaps scan the relevant extract ? I don't have Wald handy right now.
