WeylTensor¶

Weyl conformal tensor.

class gravica.weyl.WeylTensor(riemann, ricci)¶

Bases: object

Weyl tensor \(C_{abcd}\) (fully covariant).

\[C_{abcd} = R_{abcd} - \frac{2}{n-2}\bigl(g_{a[c}\,R_{d]b} - g_{b[c}\,R_{d]a}\bigr) + \frac{2}{(n-1)(n-2)}\,R\;g_{a[c}\,g_{d]b}\]

classmethod from_metric(metric)¶

Build from a MetricTensor.

property components: list[list[list[list[Expression]]]]¶: \(C_{abcd}\) indexed as [a][b][c][d].
