The Einstein field equations—which determine the geometry of spacetime in the presence of matter—contain the Ricci tensor, and so calculating the Christoffel symbols is essential. Once the geometry is determined, the paths of particles and light beams are calculated by solving the geodesic equations in which the Christoffel symbols ...
To obtain the Christoffel symbols of the second kind, find linear combinations of the above right-hand side expressions that leave only one second derivative, with coefficient $1$. Here this is easy because the metric is already in diagonal form.
- I'd like to expand on Hans Lundmark's answer because the question keeps recurring. Let $q^1,\\ldots,q^n$ denote the generalized coordinates. Intro...
- It's worth noting that if the metric is diagonal the calculations become much simpler. Explicitly, \\begin{align} &\\Gamma^{\\lambda}_{\\;\\,\\mu \ u} =...
- You can read off the Christoffel symbols from the Euler–Lagrange equations for the Lagrangian naturally defined by the metric, $L=\\frac12 g_{ij} v^...

compute the Christo el symbols in terms of the coe cients of the rst fundamental form, E, F, G, and their derivatives. Important Observation All geometric concepts and properties expressed in terms of the Christo el symbols are invariant under isometries.
With the metric in hand, we can set about computing the connection coefficients and curvature tensor. Setting da/dt, the Christoffel symbols are given by
