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. …
WebOct 16, 2024 · The covariant derivative ## \nabla_k ## acts exactly as a covariant tensor. The contravariant derivative ## \nabla^k ## is defined as $$\nabla^k= g^{kj} \nabla_j$$ and acts as a contravariant tensor. The transformation rule of the Christoffel Symbol in a flat space can be derived from the identity:

Covariant differentiation is not defined for array indices. To ensure the correct Christoffel symbols (and the correct coordinates for ordinary differentiation) are used, cov() will change the current-metric to that specified on the altmetric property of the input. spongy receptacleWebSep 4, 2024 · 1 Answer. The formula gives the components of the Lie derivative of the connection as a whole, not the Lie derivative of each Christoffel symbol which is a function. Let's assume for a moment that the connection is a ( 1, 2) tensor and compute the Lie derivative formally.
