Title: Mean curvature flow as a tool to study topology of a 4-manifold

Speaker: Doctor Zhu, Xiaobao (Renmin University of China)

Venue: Room 09 at Quan-Zhai (全斋), BICMR, Peking University

Time: Oct 30, 2012, Tuesday, 10:00 - 12:00 a.m.

Abstract: We discuss the preprint of Colding, Minicozzi and Pedersen on arXiv at Aug 29. We will start at Sect.5 of the preprint and replace the former 4 sections with a theorem of Kervaire and Milnor, which says that any closed smooth 4-dimensional manifold homotopy equivalent to S^4 can be smoothly embedded as a hypersurface.
