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. 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.

Therefore, the number of independent Christoffel symbols is obtained at most as. N × N ( N + 1) 2 = N 2 ( N + 1) 2. For example, for a general 2 -dimensional space, the total number of independent Christoffel symbols are, at most, 6.

WebThis is known as the Schwarz–Christoffel parameter problem, and its solution is the ﬁrst step in any Schwarz–Christoffel map.

WebMar 5, 2024 · In other words, there is no sensible way to assign a nonzero covariant derivative to the metric itself, so we must have ∇ X G = 0. The required correction therefore consists of replacing d / d X with. (9.4.1) ∇ X = d d X − G − 1 d G d X. Applying this to G gives zero. G is a second-rank tensor with two lower indices.
