WitrynaWe can now define the new covariant derivative: $$\nabla_\mu A^\nu=\partial_\mu A^\nu+\Gamma^\nu_{\ \mu\lambda}A^\lambda$$ And you can see that the second part of the Christoffel symbol will indeed cancel out the unwanted term, whereas its first part transforms correctly. In effect, $\nabla_\mu A^\nu$ does now transform as a proper … Witryna3 cze 2011 · They are defined by the equation. If there is a coordinate chart whose induced coordinate vector fields are orthonormal, then yes, the Christoffel symbols are 0 and the curvature is 0. But from the existence of an orthonormal basis, you can't conclude anything. (By Gram-Schmidt, such a basis exists near every point!) hbo go veep season 6
