Curvature in Riemannian Space,For a (pseudo-)Riemannian space . we can use the metric tensor . to lower the superscript of the curvature tensor ., i.e., introduce a tensor of type (4,0) with the components . We emphasize that the lowered subscript is assumed to be the .. Specifically for this reason, the components of the tensor . are denoted by ...

Surfaces with Conformal Structure,The curvature tensor . of a (pseudo-)Riemannian space χ according to Corollary 17.1, admits a decomposition of the form . where . is the Bianchi tensor with the components . the .. The latter tensor has an interesting geometric sense.
