A direct, bundle-theoretic method for defining and extending local isometries out of curvature data is developed. As a by-product, conceptual direct proofs of a classical result of Singer and a recent result of the authors are derived. A classical result of I. M. Singer [11] states that a Riemannian manifold is locally homogeneous if and only if its Riemannian curvature tensor together with its...
