Rigidity of compact quasi-Einstein manifolds with boundary
Johnatan Costa, Ernani Ribeiro, Detang Zhou
In this article, we investigate the geometry of compact quasi-Einstein manifolds with boundary. We show that a -dimensional simply connected compact quasi-Einstein manifold with…

On quasi-Einstein manifolds with constant scalar curvature
Johnatan Costa, Ernani Ribeiro, Márcio Santos
In this article, we study quasi-Einstein manifolds with constant scalar curvature. We provide a classification of compact and noncompact (possibly with boundary) -flat quasi-Ein…
