In this article we study manifolds with C0-metrics and properties of Lorentzian multiply warped products. We represent the interior Schwarzschild space–time as a multiply warped product space–time with warping functions and we also investigate the curvature of a multiply warped product with C0-warping functions. We give the Ricci curvature in terms of f1, f2 for the multiply warped products of the form M=(0,2m)×f1R1×f2S2. 
Curvature of Multiply Warped Products
In this paper, we study Ricci-flat and Einstein Lorentzian multiply warped products. We also consider the case of having constant scalar curvatures for this class of warped products. Finally, afterExpand
Curvature of multiply warped products
Abstract In this paper, we study Ricci-flat and Einstein–Lorentzian multiply warped products. We also consider the case of having constant scalar curvatures for this class of warped products.Expand
Skew CR-warped products of Kaehler manifolds
Warped product CR-submanifolds of Kaehler manifolds were introduced by Chen in [9]. In this paper, we introduce a warped product skew-CR-submanifold, which is a generalization of warped productExpand
Bakry-\'Emery Ricci curvature of doubly warped product of weighted spaces
We introduce a notion of doubly warped product of weighted graphs that is consistent with the doubly warped product in the Riemannian setting. We establish various discrete Bakry-Émery RicciExpand
The Warped Product Approach to GMGHS Spacetime
In the framework of Lorentzian multiply warped products we study the Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) spacetime and the nonsmooth geodesic motion near hypersurfaces in the interiorExpand
Warped product skew CR-submanifolds of Kenmotsu manifolds and their applications
In this paper, we introduce the notion of warped product skew CR-submanifolds in Kenmotsu manifolds. We obtain several results on such submanifolds. A characterization for skew CR-submanifolds isExpand
Parallel translation in warped product spaces: application to the Reissner-Nordström spacetime
A formal treatment of the parallel translation transformations in warped product manifolds is presented and related to those parallel translation transformations in each of the factor manifolds. AExpand
Ricci curvature of doubly warped products: weighted graphs v.s. weighted manifolds
We set forth a definition of doubly warped products of weighted graphs that is -- up to inner products of gradients of functions -- consistent with the warped product in the Riemannian setting. WeExpand
The geodesic motion near hypersurfaces in the warped products spacetime
In the framework of Lorentzian multiply warped products we study the Gibbons–Maeda–Garfinkle–Horowitz–Strominger (GMGHS) spacetime near hypersurfaces in the interior of the event horizon. We alsoExpand
Anisotropy universe in doubly warped product scheme
We study the GMGHS spacetimes to analyze the evolution of the anisotropy universe, which can be treated as a doubly warped products manifold possessing warping functions (or scale factor) having theExpand
