... G µν is given by (6.8) and T µν is the energy-momentum tensor, calculated to zeroth order in h µν . We do not include higher-order corrections to the energy-momentum tensor because the amount of energy ... pertur- bation. We define the “trace-reversed” perturbation ¯ h µν by ¯ h µν = h µν − 1 2 η µν h . (6.20) The name makes sense, since ¯ h µ µ = −h µ µ . (The Einstein tensor is simply the tr...
