Kerr metric derivation (Adler, Bazin & Schiffer)

  1. Jun 15, 2010 #1
    I have a problem understanding part of Adler, Bazin and Schiffer's (Introduction to General Relativity 2nd Edition) derivation of the Kerr metric. I would be grateful if someone could explain where I am going wrong. My problem concerns the transition from the O(m2) equation (7.15b) to (7.24). For the first term of (7.15b) I get:


    while for the second term (INCLUDING the minus sign preceding the 2 Minkowski metrics):


    Adding these 2 expressions does not produce a factor of the LHS of (7.24), although subtracting them does.

    Found my mistake; the first term should be the negative of that shown.
