WebThe Christoffel symbols measure the degree to which an observer following a straight line in coordinate space is not in free fall. Such an observer, wanting Newton's second law to hold, would then have to … WebJan 30, 2024 · In textbooks about general relativity, it is common to present the Riemann and Ricci tensors using the Christoffel symbols. This is easy to understand because it is a straightforward way to perform practical computations and the formulas one obtains are elegant and easy to grasp.

WebMar 24, 2024 · The Christoffel symbols are tensor-like objects derived from a Riemannian metric g. They are used to study the geometry of the metric and appear, for example, in the geodesic equation.
