Ricci solitons on singly warped product manifolds and applications [PDF]

open access: yes, 2023
The purpose of this article is to study implications of a Ricci soliton warped product manifold to its base and fiber manifolds. First, it is proved that if a warped product manifold is Ricci soliton then its factors are Ricci soliton.

Warped product space-times [PDF]

open access: yesClassical and Quantum Gravity, 2017
Abstract Many classical results in relativity theory concerning spherically symmetric space-times have easy generalizations to warped product space-times, with a two-dimensional Lorentzian base and arbitrary dimensional Riemannian fibers. We first give a systematic presentation of the main geometric constructions, with emphasis on the

A Study of Doubly Warped Product Immersions in a Nearly Trans-Sasakian Manifold with Slant Factor

open access: yesAdvances in Mathematical Physics, 2021
In this article, we discuss the de Rham cohomology class for bislant submanifolds in nearly trans-Sasakian manifolds. Moreover, we give a classification of warped product bislant submanifolds in nearly trans-Sasakian manifolds with some nontrivial ...

A Study of Generalized Projective P−Curvature Tensor on Warped Product Manifolds

open access: yesJournal of Mathematics, 2021
The main aim of this study is to investigate the effects of the P−curvature flatness, P−divergence-free characteristic, and P−symmetry of a warped product manifold on its base and fiber (factor) manifolds.

Warped Poisson brackets on warped products

open access: yesJournal of Geometric Mechanics, 2014
In this paper, we generalize the geometry of the product pseudo-Riemannian manifold equipped with the product Poisson structure (\cite{Nas2}) to the geometry of a warped product of pseudo-Riemannian manifolds equipped with a warped Poisson structure. We construct three bivector fields on a product manifold and show that each of them lead under certain ...

On Doubly Warped Product Manifolds [PDF]

open access: yes, 2006
We study the doubly warped product manifold M=B_h×_fF of Riemannian manifolds related to critical Riemannian metrics and conharmonic transformation, and investigate the conditions of M to be a warped product space or a Riemannian ...

open access: yesAdvances in Mathematical Physics, 2020
In this study, we attain some existence characterizations for warped product pointwise semi slant submanifolds in the setting of Sasakian space forms. Moreover, we investigate the estimation for the squared norm of the second fundamental form and further
