A short note on $f$-biharmonic hypersurfaces

Comment.Math.Univ.Carolin. 61,1 (2020) 119-126.

Abstract:In the present paper we give some properties of $f$-biharmonic hypersurfaces in real space forms. By using the $f$-biharmonic equation for a hypersurface of a Riemannian manifold, we characterize the $f$-biharmonicity of constant mean curvature and totally umbilical hypersurfaces in a Riemannian manifold and, in particular, in a real space form. As an example, we consider $f$-biharmonic vertical cylinders in $S^{2}\times \mathbb{R}$.

Keywords: $f$-biharmonic maps; $f$-biharmonic hypersurface
