The 24 pages that link to Riemann curvature tensor, each with the reason it gives.
Riemannian geometryBroader topic: It encodes the manifold's full intrinsic curvature.
Riemannian metricRelated: The metric's variation determines the manifold's intrinsic curvature.
TensorBroader topic: It is a prominent example of a tensor field built from geometric structure.
Ricci curvatureNarrower topic: Ricci curvature is its trace over two tensor indices.
Curved spacetimeBroader topic: Its components describe the local curvature represented by the model.
