リーマン曲率テンソル
1. Riemann curvature tensorIn the mathematical field of differential geometry, the Riemann curvature tensor, or Riemann–Christoffel tensor after Bernhard Riemann and Elwin Bruno Christoffel, is the most standard way to express curvature of Riemannian manifolds. It associates a tensor to each point of a Riemannian manifold (i.e. , it is a tensor field), that measures the extent to which the metric tensor is not locally isometric to a Euclidean space.
