چکیده

We show a relationship between the non-acyclic Reidemeister torsion and a zero of the acyclic Reidemeister torsion for a λ-regular SU(2) or SL(2,C)-representation of a knot group. Then we give a method to calculate the non-acyclic Reidemeister torsion of a knot exterior. We calculate a new example and investigate the behavior of the non-acyclic Reidemeister torsion associated to a 2-bridge knot and SU(2)-representations of its knot group.

The Relationship between a Zero of Acyclic Reidemeister Torsion and Non Acyclic Reidemeister Torsion

Given a λ-regular SU(2) or SL(2,C)-representation of a knot group, we show how to calculate non-abelian twisted Reidemeister torsion of its knot exterior. This method is due to considering the relationship between a zero of acyclic Reidemeister torsion and non-acyclic Reidemeister torsion. We calculate some examples and investigate the behavior of non-abelian SU(2)-twisted Reidemeister torsion ...

Limit Values of the Non-acyclic Reidemeister Torsion for Knots

We consider the Reidemeister torsion associated with SL2(C)representations of a knot group. A bifurcation point in the SL2(C)-character variety of a knot group is a character which is given by both an abelian SL2(C)representation and a non-abelian one. We show that there exist limits of the non-acyclic Reidemeister torsion at bifurcation points and the limits are expressed by using the derivati...

Multivariable Twisted Alexander Polynomial for Hyperbolic Three–manifolds with Boundary

We consider a sign–determined Reidemeister torsion with multivariables for a hyperbolic three–dimensional manifold with cusps. Using a cut and paste argument, we prove that this Reidemeister torsion is a polynomial invariant when provided with appropriate conditions on the topology of the manifold and SL2(C)representations of its fundamental group. Under such assumptions, it is proved that this...

Euclidean Geometric Invariant of Framed Knots in Manifolds

We present an invariant of a three–dimensional manifold with a framed knot in it based on the Reidemeister torsion of an acyclic complex of Euclidean geometric origin. To show its nontriviality, we calculate the invariant for some framed (un)knots in lens spaces. An important feature of our work is that we are not using any nontrivial representation of the manifold fundamental group or knot group.
