Hypersurfaces in a conformally flat space with curvature collineation (Q1178801)

Let \(\overline M^ n\) be a conformally flat Riemannian or pseudo- Riemannian manifold. The authors study the second fundamental form of a pseudo-Einstein hypersurface \(M^{n-1}\subset\overline M^ n\), under the assumption that \(\overline M^ n\) admits a certain type of translation, called a curvature collineation.
