On conformally doubly warped product Finsler manifold [PDF]

Journal of the Egyptian Mathematical Society, 2019
The aim of the present paper is to introduce the notion of conformally doubly warped product Finsler manifold (CDWPF). For such a Finsler manifold, the coefficients of Barthel connection and its curvature tensor are investigated.

Gray’s decomposition on doubly warped product manifolds and applications

Filomat, 2020
A. Gray presented an interesting $O\left( n\right) $ 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

Killing and 2-Killing 1-Forms on Poisson Doubly Warped Product Manifolds [PDF]

Mathematics
In this paper we investigate Killing and 2-Killing 1-forms on a Poisson doubly warped product manifold (PDWPM). We establish a connection between the property of 1-form on a PDWPM and its components on the factor manifolds to be Killing or 2-Killing.

Contravariant Curvatures of Doubly Warped Product Poisson Manifolds

Mathematics
In this paper, we investigate the sectional contravariant curvature of a doubly warped product manifold ( fB×bF,g˜,Π=ΠB+ΠF) equipped with a product Poisson structure Π, using warping functions and sectional curvatures of its factor manifolds (B,g˜B,ΠB ...

Geometric analysis of the pseudo-projective curvature tensor in doubly and twisted warped product manifolds

AIMS Mathematics
This study investigates the pseudo-projective curvature tensor within the framework of doubly and twisted warped product manifolds. It offers significant insights into the interaction between the pseudo-projective curvature tensor and both the base and ...

Trivial doubly warped products

Filomat
The aim of the paper is to provide new obstructions to the existence of doubly warped products. We prove that, if the factor manifolds of a doubly warped product are connected and locally product Riemannian manifolds, then, the almost product ...

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.
