      New presentations of surface braid groups 

      González-Meneses López, Juan (World Scientific Publishing, 2001)
      In this paper we give new presentations of the braid groups and the pure braid groups of a closed surface. We also give an algorithm to solve the word problem in these groups, using the given presentations.

      Vassiliev invariants for braids on surfaces 

      González-Meneses López, Juan; Paris, Luis (American Mathematical Society, 2004)
      We show that Vassiliev invariants separate braids on a closed oriented surface, and we exhibit an universal Vassiliev ...
