    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 equivalents 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.
