Jacobi vector fields and conjugate points on warped product manifolds

, 2023
In this paper, the structure of Jacobi vector fields on warped product manifolds is investigated. Many characterizations of Jacobi vector fields on warped product manifolds are obtained. Consequently, conjugate points on warped product manifolds are also

Finsler Warped Product Metrics with Special Curvature Properties

Axioms, 2023
The class of warped product metrics can often be interpreted as key space models for the general theory of relativity and theory of space–time. In this paper, we study several non-Riemannian quantities in Finsler geometry. These non-Riemannian quantities

Some Results on Warped Product Submanifolds of a Sasakian Manifold

International Journal of Mathematics and Mathematical Sciences, 2010
We study warped product Pseudo-slant submanifolds of Sasakian manifolds. We prove a theorem for the existence of warped product submanifolds of a Sasakian manifold in terms of the canonical structure 𝐹.

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

Advanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.

Warped product submanifolds in metallic Riemannian manifolds [PDF]

, 2018
In this paper, we study the existence of proper warped product submanifolds in metallic (or Golden) Riemannian manifolds and we discuss about semi-invariant, semi-slant and, respectively, hemi-slant warped product submanifolds in metallic and Golden ...

Warped Product Semi-Invariant Submanifolds of Nearly Cosymplectic Manifolds [PDF]

, 2011
We study warped product semi-invariant submanifolds of nearly cosymplectic manifolds. We prove that the warped product of the type is a usual Riemannian product of and , where and are anti-invariant and invariant submanifolds of a nearly cosymplectic ...
