摘要：
We find the necessary and sufficient conditions for a sequential warped product manifold to be a quasi-Einstein manifold. We also investigate the necessary conditions for a sequential standard static space-time and a sequential generalized Robertson-Walker space-time to be a manifold of quasi-constant curvature.
