WebSep 4, 2024 · The Lie derivative of the Christoffel symbol is L ξ Γ i j k = ∇ i ∇ j ξ k − R i j l k ξ l. How can one prove that? And why does it make sense, because Christoffel symbols are functions? I know that the last question could be irrelevant, since the correct form of the LHS of the equation should be ( L ξ Γ) i j k. But, I still cannot figure it out.

The quantity AiB i is a scalar, and to proceed we require two conditions: (1)The covariant derivative of a scalar is the same as the ordinary de-rivative. (2)The covariant derivative obeys the product rule.
