摘要
In this paper, we prove a gap result for a locally conformally flat complete non-compact Riemannian manifold with bounded non-negative Ricci curvature and a scalar curvature average condition. We show that if it has positive Green function, then it is flat. This result is proved by setting up new global Yamabe flow. Other extensions related to bounded positive solutions to a Schrodinger equation are also discussed. A global existence of Yamabe flow on a locally conformally flat complete non-compact Riemannian manifold with bounded non-negative sectional curvature is proved.
