Codazzi tensors (named after Delfino Codazzi) arise very naturally in the study of Riemannian manifolds with harmonic curvature or harmonic Weyl tensor. In fact, existence of Codazzi tensors impose strict conditions on the curvature tensor of the manifold.


Let be a n-dimensional Riemannian manifold for , let be a tensor, and let be a Levi-Civita connection on the manifold. We say that the tensor is a Codazzi Tensor if .
