CurvatureQ

• CurvatureQ[covd] yields True if covd has been defined with curvature on at least one of its vbundles, and False if it has been defined as flat. If covd is not recognized as a covariant derivative, an error message is thrown.
• CurvatureQ[covd, vbundle] yields True if covd has been defined with curvature one vbundle and False otherwise.

• See: Section 4.5.
• See also: Curvature.
• New in version 0.
