Almost conformally Einstein manifolds and obstructions
A. R. Gover
A Riemannian or pseudo-Riemannian (or conformal) structure is conformally Einstein if and only if there is a suitably generic parallel section of a certain vector bundle -- the so-…

Obstructions to conformally Einstein metrics in dimensions
A. Rod Gover, Pawel Nurowski
We construct polynomial conformal invariants, the vanishing of which is necessary and sufficient for an -dimensional suitably generic (pseudo-)Riemannian manifold to be conforma…
