In complex analysis, a Schwarz–Christoffel mapping is a conformal map of the upper half-plane or the complex unit disk onto the interior of a simple polygon. Such a map is guaranteed to exist by the Riemann mapping theorem (stated by Bernhard Riemann in 1851); the Schwarz–Christoffel formula provides an explicit construction. They were introduced independently by Elwin Christoffel in 1867 and Hermann Schwarz in 1869. WebJun 20, 2024 · I want to compute the Christoffel-symbol for a given metric.

I'm trying to understand this formula intuitively, specifically how it describes how the covariant basis varies from point to point. It seems to describe the projection of the rate of change of e i → with respect to the x j direction onto ...
WebWhat the Ricci tensor looks like in any given space is ultimately determined by what the metric is in that given space. The general steps for calculating the Ricci tensor are as follows: Specify a metric tensor (either in matrix form or the line element of the metric). Calculate the Christoffel symbols from the metric.
