Twisting Kuperberg invariants via Fox calculus and Reidemeister torsion

نویسندگان

چکیده

We study Kuperberg invariants for sutured manifolds in the case of a semidirect product an involutory Hopf superalgebra $H$ with its automorphism group $\text{Aut}(H)$. These are topological balanced 3-manifolds endowed homomorphism fundamental into $\text{Aut}(H)$ and possibly $\text{Spin}^c$ structure homology orientation. show that these computed via form Fox calculus that, if is $\mathbb{N}$-graded, they can be extended canonical way to polynomial invariants. When exterior algebra, we this invariant specializes refinement twisted relative Reidemeister torsion 3-manifolds. also give explanation our formulas terms particular group-algebra.

Reidemeister Torsion, the Thurston Norm and Harvey’s Invariants

Recently representations over non–commutative rings were used by Cochran, Harvey, Friedl–Kim and Turaev to define Alexander polynomials whose degrees give lower bounds on the Thurston norm. We first show how Reidemeister torsion relates to these invariants. We give lower bounds on the Thurston norm in terms of the Reidemeister torsion which contain all the above lower bounds and give an elegant...

Higher Franz - Reidemeister Torsion

In this expository article I will discuss the theory of higher Franz-Reidemeister torsion and its application to the construction of non-trivial classes in the algebraic K-theory of elds. I will also explain how these ideas may be used to construct classes in the cohomology of the Torelli group.

Reidemeister Franz Torsion

INTRODUCTION In this paper we discuss an approach to the study of closed, connected, oriented manifolds, with infinite fundamental group which have a special property which we call L 2-acyclicity. The first object of our exposition is to summarise in an accessible form what we have established about such manifolds in [2]. As a result of discussions on this work which occurred during the confere...

A Relationship between the Non-acyclic Reidemeister Torsion and a Zero of the Acyclic Reidemeister Torsion

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...

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 ...
