Title & Abstract
Speaker: 郭婷婷
Title: A Locally Area-minimizing Torus in a Three-manifold (M,g) with Nonnegative Rg
Abstract: The following theorem is originally due to Cai and Galloway. If (M, g) is a three-dimensional manifold with nonnegative scalar curvature, and Σ is a locally area-minimizing torus in M, then M is flat in a neighborhood of Σ. Here, 'locally area-minimizing' means that Σ has an area less than or equal to that of all nearby surfaces.
Speaker: 張茗遠
Title: Some Basic Techniques in Mean Curvature Flow
Abstract: In this talk, I will first sketch the proof of the short time existence of MCF starting from a compact hypersurface.
After deriving the evolution equations for some fundamental geometric quantities, using Hamilton's trick and maximum principle, we can deduce the comparison principle and the blow up of the second fundamental form.
If time permits, I will mention Huisken’s monotonicity formula and type I singularity, then show its application to MCF for convex closed hypersurfaces.
