WebIn the mathematical field of differential geometry, the Riemann curvature tensor or Riemann–Christoffel tensor (after Bernhard Riemann and Elwin Bruno Christoffel) is the most common way used to express the curvature of Riemannian manifolds.It assigns a tensor to each point of a Riemannian manifold (i.e., it is a tensor field).It is a local … WebJun 20, 1997 · eigenvalues as the singularity of Stiefel and Grassmann coordinates. 3. Though geometrical descriptions of the Grassmann and Stiefel manifolds are available in many references, ours is the first to use methods from numerical linear al-gebra emphasizing computational efficiency of algorithms rather than abstract general settings.
