ExtrinsicKToGradNormal

• ExtrinsicKToGradNormal[expr, imetric] transforms the extrinsic curvature tensors associated to the induced metric imetric into derivatives of its normal vector. If the second argument is a list then the function is folded sequentially on all elements.
• ExtrinsicKToGradNormal[expr] expands all induced metrics.

• See: Section 4.6.
• See also: ExtrinsicK, GradNormalToExtrinsicK.
• New in version 0.
• Last update: 25-X-2007 for version 0.9.3 of xTensor`.
