| 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 |
