给出了链路补上为零同伦的2 -桥连杆的2 -桥球上的基本简单环的完整表征。利用这一结果,我们描述了2桥环群之间的所有上子午对保持的上纯态。
We give a complete characterization of those essential simple loops on 2‐bridge spheres of 2‐bridge links which are null‐homotopic in the link complements. Using this result, we describe all upper‐meridian‐pair‐preserving epimorphisms between 2‐bridge link groups.
