Publicationes Mathematicae-Debrecen, 58(4), 587-604.0033-3883http://hdl.handle.net/11452/23181In the paper we prove that under some additional curvature condition the relations R.R = 0 and R.S = 0 are equivalent for hypersurfaces of semi-Euclidean spaces. We present also examples of hypersurfaces having the curvature tenser expressed by the square, in the sense of the Kulkarni-Nomizu product, of the Ricci tenser.eninfo:eu-repo/semantics/closedAccessMathematicsHypersurfaceStructure theoremsPseudosymmetry type manifoldRicci-semisymmetric manifoldSemisymmetric manifoldArticle0001690750000042-s2.0-0040434800587604584MathematicsSlant Submanifold; Kaehler Manifold; Sasakian Space Form
