CurvatureRelationsQ[
cd
]
returns True if all of the curvature relations for the covariant derivative
cd
have been set as automatic rules for the curvature tensors, and False otherwise.
MORE INFORMATION
The curvature relations are replacement rules that send contractions of the Riemann tensor to the Ricci tensor or Ricci scalar.
The curvature relations are usually set during the definition of a covariant derivative or metric through the option
CurvatureRelations
.
