A submanifold $\phi: M\to\mathbb E^{m} $ is called {\it biharmonic} if it satisfies
$\Delta^{2}\phi= 0$ identically, according to the author. On the other hand, G.-Y. Jiang …

A submanifold φ: M→ Em is called biharmonic if it satisfies∆ 2φ= 0 identically, according to
the author. On the other hand, G.-Y. Jiang studied biharmonic maps between Riemannian …

In this paper, we consider biconservative and biharmonic isometric immersions into the 4-
dimensional Lorentzian space form L 4 (δ) with constant sectional curvature δ. We obtain …

In this paper, we study biconservative isometric immersions into Minkowski 4-space E 1 4.
We obtain the local classification of biconservative hypersurfaces with non-diagonalizable …
