Hypersurfaces satisfying $△\vec{H}=\lambda \vec{H}$ in $\mathbb{E}_{\lowercase{s}}^{5}$

Ram Shankar Gupta, Andreas Arvanitoyeorgos

In this paper, we study hypersurfaces $M_r^4$ $(r=0,1,2,3,4)$ satisfying $△\vec{H}=\lambda \vec{H}$ ($\lambda$ a constant) in the pseudo-Euclidean space ${\mathbb{E}}_s^5$ $(…
