Streszczenie
We investigate curvature properties of hypersurfaces of a semi-Riemannian space form satisfying $R\cdot C=LQ(S,C)$, which is a curvature condition of pseudosymmetry type. We prove that under some additional assumptions the ambient space of such hypersurfaces must be semi-Euclidean and that they are quasi-Einstein Ricci-semisymmetric manifolds.
