A second-order identity for the Riemann tensor and applications / C. A. Mantica, L. G. A. Molinari. - In: COLLOQUIUM MATHEMATICUM. - ISSN 0010-1354. - 122:1(2011), pp. 69-82.
Abstract:
A second-order differential identity for the Riemann tensor is obtained, on a manifold with a symmetric connection. Several old and some new differential identities for the Riemann and Ricci tensors are derived from it. Applications to manifolds with recurrent or symmetric structures are discussed. The new structure of K-recurrency naturally emerges from an invariance property of an old identity due to Lovelock.
