WebMar 5, 2024 · In other words, there is no sensible way to assign a nonzero covariant derivative to the metric itself, so we must have ∇ X G = 0. The required correction therefore consists of replacing d / d X with. (9.4.1) ∇ X = d d X − G − 1 d G d X. Applying this to G gives zero. G is a second-rank tensor with two lower indices.
