摘要：
The purpose of this article is to investigate the structure of complete non-compact quasi-Einstein manifolds. We show that complete noncompact quasi-Einstein manifolds with lambda = 0 are connected at infinity. In addition, we provide some conditions under which quasi-Einstein manifolds with lambda < 0 are f-non-parabolic. In particular, we obtain estimates on volume growth of geodesic balls for such manifolds.
