Warped Product Submanifolds of Riemannian Product Manifolds [PDF]
Abstract and Applied Analysis, 2012 We study warped product of the type Nθ×fNT and Nθ×fN⊥, where Nθ, NT, and N⊥ are proper slant, invariant, and anti-invariant submanifolds, respectively, and we prove some basic results and finally obtain some inequalities for squared norm of second ...

On Landsberg Warped Product Metrics [PDF]
Zurnal matematiceskoj fiziki, analiza, geometrii, 2021 In the present paper the authors discuss the Finsler warped product metrics. They study the Berwald curvature of Finsler warped product metrics. They characterize the Finsler warped product metrics of isotropic Berwald curvature and deduce that they are Randers metrics (Theorem 1.2).

Warped product space-times [PDF]
Classical 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

Sequential Warped Products and Their Applications
International Electronic Journal of Geometry, 2021 In this paper, we study the sequential warped product manifolds, which are the natural generalizations of singly warped products. Many spacetime models that characterize the universe and the solutions of Einstein's field equations are known to have this new structure.

A Study of Doubly Warped Product Immersions in a Nearly Trans-Sasakian Manifold with Slant Factor
Advances 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
Journal 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 Product Pointwise Semi Slant Submanifolds of Sasakian Space Forms and their Applications
Advances 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
