Vassiliev invariants for braids on surfaces
نویسندگان
چکیده
We show that Vassiliev invariants separate braids on a closed oriented surface, and we exhibit an universal Vassiliev invariant for these braids in terms of chord diagrams labeled by elements of the fundamental group of the considered surface. 1 Definitions and statements 1.

Vassiliev Homotopy String Link Invariants
We investigate Vassiliev homotopy invariants of string links, and find that in this particular case, most of the questions left unanswered in [3] can be answered affirmatively. In particular, Vassiliev invariants classify string links up to homotopy, and all Vassiliev homotopy string link invariants come from marked surfaces as in [3], using the same construction that in the case of knots gives...
متن کاملVassiliev and Quantum Invariants of Braids
We prove that braid invariants coming from quantum gl(N) separate braids, by recalling that these invariants (properly decomposed) are all Vassiliev invariants, showing that all Vassiliev invariants of braids arise in this way, and reproving that Vassiliev invariants separate braids. We discuss some corollaries of this result and of our method of proof.
متن کاملBirman’s conjecture for singular braids on closed surfaces
Let M be a closed oriented surface of genus g ≥ 1, let Bn(M) be the braid group of M on n strings, and let SBn(M) be the corresponding singular braid monoid. Our purpose in this paper is to prove that the desingularization map η : SBn(M) → Z[Bn(M)], introduced in the definition of the Vassiliev invariants (for braids on surfaces), is injective.

متن کاملOn Finiteness of Vassiliev Invariants and a Proof of the Lin-wang Conjecture via Braiding Polynomials
Using the new approach of braiding sequences we give a proof of the Lin-Wang conjecture, stating that a Vassiliev invariant v of degree k has a value Ov(c(K)k) on a knot K, where c(K) is the crossing number of K and Ov depends on v only. We extend our method to give a quadratic upper bound in k for the crossing number of alternating/positive knots, the values on which suffice to determine uniqu...
متن کاملFree Groups and Finite Type Invariants of Pure Braids
In this paper finite type invariants (also known as Vassiliev invariants) of pure braids are considered from a group-theoretic point of view. New results include a construction of a universal invariant with integer coefficients based on the Magnus expansion of a free group and a calculation of numbers of independent invariants of each type for all pure braid groups.
