Sinica-NCTS Reading Seminar on Geometry 主講者: 陳志偉博士(台灣大學) 講題: Connected sum of manifolds with positive scalar curvature 時間: 2012-05-07 (Mon.)  16:00 - 17:00 地點: 數學所 617 研討室 (台大院區) Abstract: We will go over the surgery procedure adapted by R. Schoen and S.-T. Yau in their article: On the structure of manifolds with positive scalar curvature, Manuscripta Math. 28, (1979), 159-183. The goal of this surgery is to prove that any manifold constructed from doing connected sum along submanifolds (with codimension greater or equal to 3) of two manifolds with positive scalar curvature also admits a metric with positive scalar curvature. || Close window ||
