| contents | A submanifold $ϕ:M\to \mathbb E^{m}$ is called {\it biharmonic} if it satisfies $Δ^{2}ϕ=0$ identically, according to the author. On the other hand, G.-Y. Jiang studied biharmonic maps between Riemannian manifolds as critical points of the bienergy functional, and proved that biharmonic maps $φ$ are characterized by vanishing of bitension $τ_{2}$ of $φ$. During last three decades there has been a growing interest in the theory of biharmonic submanifolds and biharmonic maps.
The study of $H$-submanifolds of $\mathbb E^{m}$ were derived from biharmonic submanifolds by only requiring the vanishing of the tangential component of $Δ^{2}ϕ$. In 2014, R. Caddeo et. al. named a submanifold $M$ in any Riemannian manifold ``biconservative'' if the stress-energy tensor $\hat S_{2}$ of bienergy satisfies ${\rm div}\, \hat S_{2}=0$. Caddeo et. al. also shown that a Euclidean submanifolds is an $H$-submanifold if and only if the tangential component of $τ_{2}$ vanishes and hence the notions of $H$-submanifolds and of biconservative submanifolds coincide for Euclidean submanifolds.
The first results on biconservative hypersurfaces were proved by T. Hasanis and T. Vlachos, where they called such hypersurfaces {\it H-hypersurfaces} in 1995. Since then biconservative submanifolds has attracted many researchers and a lot of interesting results were obtained. The aim of this article is to provide a comprehensive survey on recent developments on biconservative submanifolds done most during the last decade. |
