扭曲Alexander不变量的互易性

On reciprocality of twisted Alexander invariants

Jonathan A. Hillman, Daniel S. Silver, Susan G. Williams

摘要:

给定一个纽结和它的群的SL(n,C)表示,该表示与它的对偶共轭,即用它的逆转置替换每个矩阵的表示,相关联的扭曲里德迈斯特挠率是倒数。给出了一个纽结群和SL(3,Z)表示的例子,SL(3,Z)表示不与其对偶共轭,且扭曲的Reidemeister挠率不互逆.

英文摘要:

Given a knot and an SL(n,C) representation of its group that is conjugate to its dual, the representation that replaces each matrix with its inverse-transpose, the associated twisted Reidemeister torsion is reciprocal. An example is given of a knot group and SL(3,Z) representation that is not conjugate to its dual for which the twisted Reidemeister torsion is not reciprocal.
