Derivation of christoffel symbols

WebIn the mathematical field of differential geometry, the Riemann curvature tensor or Riemann–Christoffel tensor (after Bernhard Riemann and Elwin Bruno Christoffel) is the most common way used to express the curvature of Riemannian manifolds.It assigns a tensor to each point of a Riemannian manifold (i.e., it is a tensor field).It is a local … WebIn the case of a curved space (time), what the Christoffel symbols do is explain the inhomogenities/curvature/whatever of the space (time) itself. As far as the curvature tensors--they are contractions of each other. The Riemann tensor is simply an anticommutator of derivative operators-- R a b c d ω d ≡ ∇ a ∇ b ω c − ∇ b ∇ a ω c.
