Twisted -torsion on the character variety
Léo Bénard, Jean Raimbault
We define a twisted -torsion on the character variety of 3-manifold and study some of its properties. In the case where is hyperbolic of finite volume, we prove that t…

Asymptotics of twisted Alexander polynomials and hyperbolic volume
Léo Bénard, Jérôme Dubois, Michael Heusener +1
For a hyperbolic knot and a natural number n, we consider the Alexander polynomial twisted by the n-th symmetric power of a lift of the holonomy. We establish the asymptotic behavi…

A multivariable Casson-Lin type invariant
Léo Bénard, Anthony Conway
We introduce a multivariable Casson-Lin type invariant for links in . This invariant is defined as a signed count of irreducible representations of the…
