    A curvature condition for a twisted product to be a warped product
    (Springer-verlag, 2001) Fernández-López, M; García-Río, E; Kupeli, DN; Ünal, B
    It is shown that a mixed Ricci-flat twisted product semi-Riemannian manifold can be expressed as a warped product semi-Riemannian manifold. Asa consequence, any Einstein twisted product semi-Riemannian manifold is in fact, a warped product serni-Riemannian manifold.
