摘要
最近Vaughan Jones证明了R. Thompson群以自然方式编码所有纽结,而的某个子群编码所有有向纽结。我们回答了Jones关于的几个问题。特别地,我们证明子群由生成(其中为的标准生成元),并且同构于——即所有斜率为的幂、断点为-进有理数的的类似物。我们还证明了与其可公度子群重合。因此在上的置换表示的线性化是不可约的。

备注
First draft, 14 pages; v2: Second draft, added Section 5 generalizing the main results from $n=2$ to arbitrary $n>1$. v3: Added a subsection about natural homomorphisms and caret replacement homomorphisms v4: Added a section proving, in particular, that the Thompson index of a link is bounded by a linear function in the number of crossings in a link diagram, added some open problems
