Dubois挠率、A-多项式与量子不变量

Dubois' Torsion, A-polynomial and Quantum Invariants

Charles Frohman, Joanna Kania-Bartoszynska

摘要:

它表明,结具有足够的经常字符品种的Dubois挠检测的A-多项式的结。给出了Dubois挠率积分的一个整体公式。该公式看起来像是纽结补的二重的Witten-Reshetikhin-Turaev不变量的公式的热核正则化。Dubois挠率是由Reidemeister挠率的平方根导出的纽结补的二重数的特征标变化量的一个测度的推广。这被用来激发关于量子不变量检测A-多项式的猜想。

英文摘要:

It is shown that for knots with a sufficiently regular character variety the Dubois' torsion detects the A-polynomial of the knot. A global formula for the integral of the Dubois torsion is given. The formula looks like the heat kernel regularization of the formula for the Witten-Reshetikhin-Turaev invariant of the double of the knot complement. The Dubois' torsion is recognized as the pushforward of a measure on the character variety of the double of the knot complement coming from the square root of Reidemeister torsion. This is used to motivate a conjecture about quantum invariants detecting the A-polynomial.
