Abstract

In this paper we confirm a folklore conjecture which suggests that for a complete noncompact manifold \(M\) of finite volume with sectional curvature \(-1 \leq K \leq 0\), if the universal cover of \(M\) is a visibility manifold, then the fundamental group of each end of \(M\) is almost nilpotent.

论非正曲率有限体积非紧凑流形的末端

在本文中，我们证实了一个民间猜想，即对于一个具有截面曲率（-1 \leq K \leq 0\）的有限体积的完整非紧密流形（M\），如果（M\）的普盖是一个可见流形，那么（M\）的每个端部的基群几乎都是零potent。
