On doubly warped product Finsler manifolds [PDF]
Nonlinear Analysis: Real World Applications, 2012 In this paper, we introduce horizontal and vertical warped product Finsler manifold. We prove that every C-reducible or proper Berwaldian doubly warped product Finsler manifold is Riemannian. Then, we find the relation between Riemmanian curvatures of doubly warped product Finsler manifold and its components, and consider the cases that this manifold ...

On doubly warped product immersions [PDF]
Journal of Geometry, 2014 In this paper we study fundamental geometric properties of doubly warped product immersion which is an extension of warped product immersion. Moreover, we study geometric inequality for doubly warped products isometrically immersed in arbitrary Riemannian manifolds.

Differential Geometry and its Applications, 2001 The author studies the completeness of Lorentzian doubly warped products with metrics of the form \(-f^2 dt^2\oplus b^2g_F\) for positive functions \(f\) on a Riemannian manifold \(F\), \(b\) on an interval \((c,d)\).

A Note on Doubly Warped Product Contact CR-Submanifolds in trans-Sasakian Manifolds
Acta Mathematica Hungarica, 2007 Warped product CR-submanifolds in Kaehlerian manifolds were intensively studied only since 2001 after the impulse given by B.Y. Chen. Immediately after, another line of research, similar to that concerning Sasakian geometry as the odd dimensional version

Gray’s decomposition on doubly warped product manifolds and applications
Filomat, 2020 A. Gray presented an interesting O(n) invariant decomposition of the covariant derivative of the Ricci tensor. Manifolds whose Ricci tensor satisfies the defining property of each orthogonal class are called Einstein-like manifolds. In the present paper, we answered the following question: Under what condition(s), does a factor manifold Mi ...

F-Harmonic Maps between Doubly Warped Product Manifolds [PDF]
Mathematics, 2017 In this paper, some properties of F -harmonic and conformal F -harmonic maps between doubly warped product manifolds are studied and new examples of non-harmonic F -harmonic maps are constructed.

Einstein Doubly Warped Product Poisson Manifolds
SymmetryIn this paper, we study Einstein doubly warped product Poisson manifolds. First, we provide necessary and sufficient conditions for a doubly warped product manifold (M=Bf×bF,g,Π), equipped with a Poisson structure Π to be a contravariant Einstein manifold.

Doubly warped product submanifolds of (κ,μ)-contact metric manifolds
Annales Polonici Mathematici, 2011 We establish sharp inequalities for C-totally real doubly warped product submanifolds in (kappa, mu)-contact space forms and in non-Sasakian (kappa, mu)-contact metric manifolds.

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 ...
