Ambrose-Singer theorem



For connections on vector bundles

Let M be a differential manifold, E a vector bundle over M, and \nabla a connection on E. Let p \in M. Then, the Lie algebra of the restricted holonomy group for \nabla at p is the subalgebra of the Lie algebra of all endomorphisms of E_p, generated by the values R(v,w) where v,w \in T_pM.

The significance of this is that the Riemann curvature tensor is in some sense, the differential of the holonomy at the point. Fill this in later
