Rigidity of Schouten Tensor under Conformal Deformation
Mijia Lai, Guoqiang Wu
We obtain some rigidity results for metrics whose Schouten tensor is bounded from below after conformal transformations. Liang Cheng recently proved that a complete, nonflat, local…

Shrinkers with curvature pinching conditions are compact
Guoqiang Wu, Jia-Yong Wu
In this paper, we give various curvature pinching conditions such that shrinkers are compact. On one hand, we prove that shrinkers with positive Ricci curvature are compact when th…
