摘要
We study generalized m-quasi-Einstein manifolds with constant scalar curvature. First, we establish a classification of generalized m-quasi-Einstein manifolds with parallel Ricci tensor. Second, and particularly, if an m-quasi-Einstein manifold possesses constant scalar curvature then we determine the scalar curvature in explicit form and show that which values are attainable by presenting examples.
