Abstract:For some families of two-bridge knots, including double twist knots with genus at least four, we determine precisely the set of integers $ n>1$ such that the fundamental group of the $ n$-fold cyclic branched cover of the 3-sphere along these knots is left-orderable. There are knots, including the figure-eight knot, for which this set is empty. We give the first class of hyperbolic knots, not of this type, for which these integers can be completely determined.

左排序,分支覆盖和双扭结

摘要:对于某些两桥结的家族,包括至少四个属的双扭结,我们精确地确定了整数的集合,$ n> 1 $使得$ n $沿着这些结保留了3-球体的-折叠循环分支覆盖的基本群-可订购的。有一些打结,包括八字形打结,这套结是空的。我们给出第一类双曲型结,不是这种类型的双曲型结,可以完全确定这些整数。
