树型Hopf铅垂中的Hopf带
Hopf bands in arborescent Hopf plumbings
摘要:
对于一个正的霍普夫铅垂树型Seifert表面$S$,我们研究了一组霍普夫带$H\subset S$,直到同源和单值的作用。塞弗特曲面的分类是有限的,这是密切相关的有限考克斯特群的分类。
英文摘要:
For a positive Hopf plumbed arborescent Seifert surface $S$, we study the set of Hopf bands $H\subset S$, up to homology and up to the action of the monodromy. The classification of Seifert surfaces for which this set is finite is closely related to the classification of finite Coxeter groups.
