- ItemFour-dimensional homogeneous manifolds satisfying some Einstein-like conditions(Kodai Mathematical Journal, 2020-10) García-Río, Eduardo; Haji-Badali, Ali; Mariño-Villar, Rodrigo; Vázquez-Abal, M. ElenaWe classify four-dimensional homogeneous manifolds satisfying some generalized Einstein conditions.
- ItemLocally conformally flat weakly-Einstein manyfolds(Archiv der Mathematik, 2018-11-21) García-Río, Eduardo; Haji-Badali, Ali; Mariño-Villar, Rodrigo; Vázquez-Abal, M. ElenaIt is shown that locally conformally flat weakly-Einstein manifolds are either locally symmetric, and hence a product Nm1(c) × Nm2(−c), or other-wise they are locally some specific warped product metrics I ×f N(c). As an application we classify weakly-Einstein hypersurfaces in the Euclidean space.
