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…

Closed generalized Einstein manifolds with radially flat Ricci curvature
Seungsu Hwang, Marcio Santos, Gabjin Yun
In this paper, we show that a closed -dimensional generalized -Einstein manifold of constant scalar curvature with weakly radially zero Ricci curvature is isometric t…
