Twisting Alexander Invariants with Periodic Representations
نویسندگان
چکیده
Twisted Alexander invariants have been defined for any knot and linear representation of its group π. The invariants are generalized for any periodic representation of the commutator subgroup π. Properties of the new twisted invariants are given. Under suitable hypotheses, reciprocality and bounds on the moduli of zeros are obtained. A topological interpretation of the Mahler measure of the invariants is presented.

Virtual Knot Invariants from Group Biquandles and Their Cocycles
A group-theoretical method, via Wada’s representations, is presented to distinguish Kishino’s virtual knot from the unknot. Biquandles are constructed for any group using Wada’s braid group representations. Cocycle invariants for these biquandles are studied. These invariants are applied to show the non-existence of Alexander numberings and checkerboard colorings.
متن کاملKnots, Links and Representation Shifts
Introduction. The group π1(S − k) of a knot k contains an extraordinary amount of information. From combined results of W. Whitten [Wh] and M. Culler, C. McA. Gordon, J. Luecke and P.B. Shalen [CuGoLuSh] it is known that there are at most two distinct unoriented prime knots with isomorphic groups. Unfortunately, knot groups are generally difficult to use. Knot groups are usually described by pr...
متن کاملT matrices for the superU(1,1) WZW model: Application to surgery and three manifolds invariants based on the Alexander-Conway polynomial,” Nucl. Phys. B389
We carry on (in a self contained fashion) the study of the Alexander Conway invariant from the quantum field theory point of view started in [1]. We investigate for that purpose various aspects of WZW models on supergroups. We first discuss in details S and T matrices for the U (1, 1) super WZW model and obtain, for the level k an integer, new finite dimensional representations of the modular g...
متن کاملInvariants of Colored Links and a Property of the Clebsch-gordan Coefficients of U Q (g)
Abstract. We show that multivariable colored link invariants are derived from the roots of unity representations of Uq(g). We propose a property of the Clebsch-Gordan coefficients of Uq(g), which is important for defining the invariants of colored links. For Uq(sl2) we explicitly prove the property, and then construct invariants of colored links and colored ribbon graphs, which generalize the m...
متن کاملAsymptotic Vassiliev Invariants for Vector Fields
We analyse the asymptotical growth of Vassiliev invariants on non-periodic flow lines of ergodic vector fields on domains of R. More precisely, we show that the asymptotics of Vassiliev invariants is completely determined by the helicity of the vector field. As an application, we determine the asymptotic Alexander and Jones polynomials and give a formula for the asymptotic Kontsevich integral.
