关于纽结的AJ猜想

On the AJ conjecture for knots

Thang T. Q. Le, Anh T. Tran

摘要:

我们证实了AJ猜想[Ga 04],该猜想将满足一定条件的双曲节的A-多项式和有色琼斯多项式联系起来。特别是,我们证明了该猜想对于某些类别的双桥结和椒盐卷饼结也成立。这扩展了第一作者在[Le 06]中的结果,在那里他建立了一个大类的二桥结,包括所有的扭曲结的AJ猜想。在此过程中,我们显式地计算了(-2,3,2n +1)-pretzel纽结的纽结群的泛特征标环,并证明了它对所有整数n都是约化的。

英文摘要:

We confirm the AJ conjecture [Ga04] that relates the A-polynomial and the colored Jones polynomial for those hyperbolic knots satisfying certain conditions. In particular, we show that the conjecture holds true for some classes of two-bridge knots and pretzel knots. This extends the result of the first author in [Le06] where he established the AJ conjecture for a large class of two-bridge knots, including all twist knots. Along the way, we explicitly calculate the universal character ring of the knot group of the (-2,3,2n+1)-pretzel knot and show that it is reduced for all integers n.
