WEYL COLLINEATIONS THAT ARE NOT CURVATURE COLLINEATIONS
WEYL COLLINEATIONS THAT ARE NOT CURVATURE COLLINEATIONS
Though the Weyl tensor is a linear combination of the curvature tensor, Ricci tensor and Ricci scalar, it does not have all and only the Lie symmetries of these tensors since it is possible, in principle, that "asymmetries cancel." Here we investigate if, when and how the symmetries can be …
