AI总结:

研究3-流形的拓扑体积不变量,定义为M中双曲链补的最小体积,给出渐近紧界并分类体积≤3.07的非双曲闭3-流形。

摘要:

本文研究了一个称为拓扑体积的3-流形实值拓扑不变量。对于给定的3-流形M,它定义为M中(可能为空)双曲链补的最小体积。给出了该不变量的各种细化,确定了渐近紧的上界和下界,并分类了所有拓扑体积不超过3.07的非双曲闭3-流形。此外,证明了对于除有限个透镜空间外的所有透镜空间,体积最小化者是通过对Whitehead链补或其姐妹流形的一个尖点进行Dehn填充得到的。

英文摘要:

This paper investigates a real-valued topological invariant of 3-manifolds called topological volume. For a given 3-manifold M it is defined as the smallest volume of the complement of a (possibly empty) hyperbolic link in M. Various refinements of this invariant are given, asymptotically tight upper and lower bounds are determined, and all non-hyperbolic closed 3-manifolds with topological volume of at most 3.07 are classified. Moreover, it is shown that for all but finitely many lens spaces, the volume minimiser is obtained by Dehn filling one of the cusps of the complement of the Whitehead link or its sister manifold.
