Einstein-like warped product manifolds / C.A. Mantica, S. Shenawy. - In: INTERNATIONAL JOURNAL OF GEOMETRIC METHODS IN MODERN PHYSICS. - ISSN 0219-8878. - 14:11(2017), pp. 1750166.1750166-1-1750166.1750166-11. [10.1142/S0219887817501663]
Abstract:
In this paper, it is proved that the fiber manifold M-2 of a warped product manifold M = M-1 x(f) M-2 inherits the Einstein-like class type of M whereas the base manifold does under some conditions. Some related results are considered.
