第二作者和Hara引入了基本三支曲面的概念,这是对3流形中基本嵌入曲面概念的推广。我们证明了任何基本群至少有4阶的3流形都存在一个基本的三支曲面。
The second author and Hara introduced the notion of an essential tribranched surface that is a generalisation of the notion of an essential embedded surface in a 3-manifold. We show that any 3-manifold for which the fundamental group has at least rank four admits an essential tribranched surface.
