三维流形Perelman坍缩定理的一个简单证明

A simple proof of Perelman's collapsing theorem for 3-manifolds

Jianguo Cao, Jian Ge

摘要:

我们将简化由Shioya-Yamaguchi和Morgan-Tian给出的关于三维流形的Perelman坍缩定理的早期证明。除其他外,我们使用佩雷尔曼的临界点理论(例如,多锥奇异性理论和他的纤维化理论)的Alexandrov空间,以构建所需的局部塞弗特纤维化结构的折叠3-流形。Perelman坍缩定理的证明是Perelman证明Thurston关于三维流形分类的几何化猜想的最后一步。我们对佩雷尔曼坍缩定理的证明几乎是独立的,非专家和高级研究生都可以使用。Perelman三维流形的坍缩定理可以看作是隐函数定理的推广

英文摘要:

We will simplify earlier proofs of Perelman's collapsing theorem for 3-manifolds given by Shioya-Yamaguchi and Morgan-Tian. Among other things, we use Perelman's critical point theory (e.g., multiple conic singularity theory and his fibration theory) for Alexandrov spaces to construct the desired local Seifert fibration structure on collapsed 3-manifolds. The verification of Perelman's collapsing theorem is the last step of Perelman's proof of Thurston's Geometrization Conjecture on the classification of 3-manifolds. Our proof of Perelman's collapsing theorem is almost self-contained, accessible to non-experts and advanced graduate students. Perelman's collapsing theorem for 3-manifolds can be viewed as an extension of implicit function theorem
