WebSep 4, 2014 · You say the Christoffel symbols are a "coordinate expression" of the Levi-Civita connection, which of course I agree with, but then you say that you can express them in an "invariant representation" (which I assume you mean coordinate-independent), without showing how such a construction is constructed. Can you elaborate? Sep 4, 2014 WebOct 23, 2024 · CHRISTOFFEL SYMBOLS In general, Christoffel symbols are related to the metric in the following way: Γ μ ν σ = 1 2 g σ ρ ( ∂ μ g ν ρ + ∂ ν g ρ μ − ∂ ρ g μ ν), ∂ μ ≡ ∂ ∂ x μ

The connection coefficients obtained in this way are symmetric and independent of the coordinates of points of the manifold.
In mathematics and physics, the Christoffel symbols are an array of numbers describing a metric connection. The metric connection is a specialization of the affine connection to surfaces or other manifolds endowed with a metric, allowing distances to be measured on that surface.
