On doubly warped product of complex finsler manifolds

Acta Mathematica Scientia, 2016
Abstract Let ( M 1 , F 1 ) and ( M 2 , F 2 ) be two strongly pseudoconvex complex Finsler manifolds. The doubly wraped product complex Finsler manifold ( f 2 M 1 × f 1 M 2 , F ) of ( M 1 , F 1 ) and ( M 2 , F 2 ) is the product manifold M 1 × M 2 endowed with the warped product complex Finsler metric F 2 = f 2 2 F 1

Doubly warped product CR-submanifolds in locally conformal Kähler manifolds

Monatshefte für Mathematik, 2007
If \((B,g_B)\) and \((F,g_F)\) are Riemannian manifolds and \(b:B\to(0,\infty)\) and \(f:F\to(0,\infty)\) are smooth functions, then the doubly warped product \(M={}_fB\times{}_bF\) is defined to be the product manifold \(B\times F\) endowed with the Riemannian metric \(g=f^2g_B\oplus b^2g_F\) [see e.g. \textit{B. Ünal}, Differ. Geom. Appl. 15, No.

𝜁 (Ric)-vector fields on doubly warped product manifolds

Istanbul Journal of Mathematics, 2023
We investigate 𝜁 (Ric)-vector fields on doubly warped product manifolds. We obtain some results when the vector field is also 𝜁 (Ric) on factor manifolds.We prove that if a vector field is a 𝜁 (Ric)-vector field on a doubly warped product manifold, it is also a 𝜁 (Ric)-vector field on the factor manifolds under certain conditions.

Mixed doubly sequential warped product manifolds

Physica Scripta
Abstract This research aims to expand the understanding of solutions to Einstein’s field equations by introducing a new class of warped product manifolds, specifically mixed doubly sequential manifolds. The study delves into the geometry of these manifolds by analyzing critical metrics, including curvature tensors, covariant derivatives,

Doubly warped product manifolds with the structure of hyperbolic Ricci solitons

Physica Scripta
Abstract In this paper we study hyperbolic Ricci solitons on doubly warped product manifolds. The necessary conditions are obtained for a hyperbolic Ricci soliton with the structure of a doubly warped product to be an Einstein manifold when we consider the potential field as a Killing or a conformal vector field.
