Abstract: We discuss some recent results on complete Kahler manifolds with nonnegative Ricci curvature:
1. the invariance of average of scalar curvature at infinity
2. boundedness of integral of higher power of Ric
3. A rigidity result for Kahler Ricci flat metric

Biography: Gang Liu is a Professor at East China Normal University. His research interest is in complex geometry and geometric analysis. The main contribution includes the classification of noncompact 3-manifolds with nonnegative curvature, Gromov-Haudorff limits of Kahler manifolds with Ricci curvature lower bound. He was invited to ICM 45 mins talk in 2022.
