Contact CR-Warped product submanifolds in Kenmotsu space forms
Abstract: In the present paper, we give a necessary and sufficient condition for contact CR-warped product to be contact CR-product in Kenmotsu space forms.
متن کاملHolography of asymmetrically warped space-times
We study the holographic dual of asymmetrically warped space-times, which are asymptotically AdS. The self-tuning of the cosmological constant is reinterpreted as a cancellation of the visible sector stress-energy tensor by the contribution of a hidden CFT, charged under a spontaneously broken global symmetry. The apparent violation of 4D causality due to bulk geodesics is justified by consider...
متن کاملWarped Product Submanifolds in Quaternion Space Forms
B.Y. Chen [3] established a sharp inequality for the warping function of a warped product submanifold in a Riemannian space form in terms of the squared mean curvature. For a survey on warped product submanifolds we refer to [4]. In [8], we established a similar relationship between the warping function f (intrinsic structure) and the squared mean curvature and the holomorphic sectional curvatu...

متن کاملComment on Ricci Collineations for Type B Warped Space-times
We present two counter examples to the paper by Carot et al. in Gen. Rel. Grav. (1997). 29 1223 and show that the results obtained are correct but not general. (x α)) are a pair of pseudo-Riemannian manifolds with coordinate functions x A (A, B, ... = 1, 2) and x α (α, β, ... = 3, 4) respectively. Let Φ(x C) be a real valued function on M 1 and M = M 1 × M 2 be the product manifold (type B warp...
