Doubly warped product CR-submanifolds in a locally conformal Kaehler space form

, 2008
Recently, the present authors considered doubly warped product CR-submanifolds in a locally conformal Kaehler manifold and got some inequalities about the length of the second fundamental form.

GRADIENT $\rho$-EINSTEIN SOLITONS AND APPLICATIONS

In this paper, we mainly study gradient $\rho$-Einstein solitons on doubly warped product manifolds. More explicitly, we obtain necessary and sufficient conditions for a doubly warped product manifold to be a gradient $\rho$-Einstein soliton.

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

AIMS Mathematics
<p>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 fiber manifolds. The research highlights key geometric characteristics of the base and fiber

Pointwise bi-slant doubly warped product submanifolds in para-Kaehler manifolds

Filomat
In this article, we consider pointwise slant and pointwise bi-slant submanifolds whose ambient spaces are para-Kaehler manifolds. We prove that there exist pointwise bi-slant K =k2 K?1 ? k1 K?2 non-trivial doubly warped product type 1-2 submanifolds whose ambient spaces are para-Kaehler manifolds by constructing examples.

Quasi-conformal curvature tensor on sequential doubly warped product manifolds with applications

The European Physical Journal C
Abstract This paper introduces a comprehensive geometric framework that bridges two important but previously disconnected areas of Riemannian geometry: the theory of sequential doubly warped product (SDWP) manifolds and the theory of quasi-conformal curvature tensors.

Pinching Results for Doubly Warped Products’ Pointwise Bi-Slant Submanifolds in Locally Conformal Almost Cosymplectic Manifolds with a Quarter-Symmetric Connection

Symmetry
In this research paper, we establish geometric inequalities that characterize the relationship between the squared mean curvature and the warping functions of a doubly warped product pointwise bi-slant submanifold. Our investigation takes place in the context of locally conformal almost cosymplectic manifolds, which are equipped with a quarter ...

Impact of pseudo-projective curvature tensor on sequential doubly warped product manifolds with physical applications

The European Physical Journal Plus
Abstract This paper investigates the geometric and physical properties of the pseudo-projective curvature tensor in the context of Sequential Doubly Warped Product Manifolds (SDWPM). We derive comprehensive expressions for this tensor’s components and establish precise necessary and sufficient conditions under which a SDWPM becomes pseudo ...
