The warped product of holomorphic Lie algebroids
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 We introduce the warped product of two holomorphic Finsler algebroids and we define a complex Finsler function on it. We study the Chern-Finsler connections of the bundles and of their product and we investigate their curvatures.

A DDVV INEQUALITY FOR SUBMANIFOLDS OF WARPED PRODUCTS [PDF]
Bulletin of the Australian Mathematical Society, 2017 We prove a DDVV inequality for submanifolds of warped products of the form $I\times _{a}\mathbb{M}^{n}(c)$, where $I$ is an interval and $\mathbb{M}^{n}(c)$ is a real space form of curvature $c$. As an application, we give a rigidity result for submanifolds of $\mathbb{R}\times _{e^{\unicode[STIX]{x1D706}t}}\mathbb{H}^{n}(c)$.

Einstein Hypersurfaces of Warped Product Spaces
Results in Mathematics, 2022 We consider Einstein hypersurfaces of warped products $I\times_ω\mathbb Q_ε^n,$ where $I\subset\mathbb R$ is an open interval and $\mathbb Q_ε^n$ is the simply connected space form of dimension $n\ge 2$ and constant sectional curvature $ε\in\{-1,0,1\}.$ We show that, for all $c\in\mathbb R$ (resp.

CRITICAL POINTS AND WARPED PRODUCT METRICS [PDF]
Bulletin of the Korean Mathematical Society, 2004 The authors prove a rigidity theorem showing that no warped products of dimension 3 can satisfy a certain Euler-Lagrange equation involving the total scalar curvature functional unless it is isometric to the standard sphere.

Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2020 Summary: We give a new characterization for doubly warped products by using the geometry of their canonical foliations intersecting perpendicularly. We also give a necessary and sufficient condition for a doubly warped product to be a warped or a direct product.
