Weakly Einstein hypersurfaces in space forms

Jihun Kim, Yuri Nikolayevsky, JeongHyeong Park

A Riemannian manifold $(M, g)$ is called \emph{weakly Einstein} if the tensor $R_{iab c} R_{j}^{ab c}$ is a scalar multiple of the metric tensor $g_{ij}$ . We give a complete classifi…

On weakly Einstein Lie groups

Yunhee Euh, Sinhwi Kim, Yuri Nikolayevsky +1

A Riemannian manifold is called \emph{weakly Einstein} if the tensor $R_{iab c} R_{j}^{ab c}$ is a scalar multiple of the metric tensor $g_{ij}$ . We consider weakly Einstein Lie gro…
