Bi-warped product submanifolds of nearly Kaehler manifolds
Siraj Uddin, Bang-Yen Chen, Awatif AL-Jedani +1
We study bi-warped product submanifolds of nearly Kaehler manifolds which are the natural extension of warped products. We prove that every bi-warped product submanifold of the for…

On Curvature properties of Nariai Spacetimes
Absos Ali Shaikh, Dhyanesh Chakraborty
The charged Nariai spacetimes are the exact solutions of Einstein-Maxwell field equations with positive cosmological constant and such a spacetime is the direct topological product…
