Abstract:We show that Vassiliev invariants separate braids on a closed oriented surface, and we exhibit a universal Vassiliev invariant for these braids in terms of chord diagrams labeled by elements of the fundamental group of the surface.

Keywords:Braid   surface   Vassiliev invariant   finite type invariant
