WebEhresmann's Theorem. Let f: X → B be a holomorphic submersive morphism. For a point b of B, we denote the fiber of f over b by X b.Fix a point 0 in B.Ehresmann's theorem guarantees that there is a small open neighborhood U around 0 in which f becomes a fiber bundle. That is, f−1(U) is diffeomorphic to X 0 × U.In particular, the composite map WebThe Riemann curvature tensor is also the commutator of the covariant derivative of an arbitrary covector with itself:;; =. This formula is often called the Ricci identity. This is the classical method used by Ricci and Levi-Civita to obtain an expression for the Riemann curvature tensor. This identity can be generalized to get the commutators for two …
