| Abstract: | We determine curvature properties of pseudosymmetric type of certain warped product manifolds, and in particular of generalized Robertson–Walker spacetimes, with Einsteinian or quasi-Einsteinian fibre. |
| Keywords: | quasi-Einstein manifold Warped product manifold Generalized Robertson–Walker spacetime Pseudosymmetric manifold Ricci-pseudosymmetric manifold Tachibana tensor |
