f-Biharmonic maps between doubly warped product manifolds
f-Biharmonic maps doubly warped product manifolds
2018/4/19
In this paper, by applying the first variation formula of $f$-bi-energy given in \cite{OND}, we study $f$-biharmonic maps between doubly warped product manifolds $M\times_{(\mu,\lambda)}N$. Under impo...
Warped product Einstein metrics over spaces with constant scalar curvature
Warped product Einstein metrics spaces constant scalar curvature
2011/2/21
In this paper we study warped product Einstein metrics over spaces with constant scalar curvature. We call such a manifold rigid if the universal cover of the base is Einstein or is isometric to a pro...
A Condition for Warped Product Semi-Invariant Submanifolds to be Riemannian Product Semi-Invariant Submanifolds in Locally Riemannian Product Manifolds
Real space form Riemannian product and Warped product
2010/2/25
In this article, we give a necessary and sufficient condition for warped product semi-invariant submanifolds to be Riemannian product semi-invariant submanifolds in a locally Riemannian product manifo...

Riemannian Warped Product Manifold Vertical and Horizontal Distributions Pseudo-Umbilical Submanifold Curvature-Invariant Submanifold
2010/3/1
In this paper, we generalize the geometry of the invariant submanifolds of Riemannian product manifold to the geometry of the invariant submanifolds of Riemannian warped product manifold. We investiga...
