| Abstract: | In this paper we introduce the framed pure braid group on n strands of an oriented surface, a topological generalisation of the pure braid group P n . We give different equivalent definitions for framed pure braid groups and we study exact sequences relating these groups with other generalisations of P n , usually called surface pure braid groups. The notion of surface framed braid groups is also introduced. |
