我们应用渐近锥的概念来区分 3 流形基本群的拟等距类。我们证明 Haken 流形中 Seifert 分量的存在是其基本群的拟等距不变量。
We apply the concept of asymptotic cone to distinguish quasi-isometry classes of fundamental groups of 3-manifolds. We prove that the existence of a Seifert component in a Haken manifold is a quasi-isometry invariant of its fundamental group.
