Speaker: 许奕彦,Peking University Inviter:数学所 Title: Convergence of metrics under self-dual Weyl tensor and Scalar curvature bounds Time & Venue: 2013.3.12 2:00pm S509 Abstract: In this talk, we will talk about some compactness theorems in Riemannian geometry. More precisely, we establish a compactness theorem for the metrics with bounded self-dual Weyl tensor and Scalar curvature. The key step is to estimate the harmonic radius, where we use the blow up analysis. The result is motivated by, and may be applied to the Calabi flow on complex surfaces Affiliation:
