On p-almost direct products and residual properties of pure braid groups of nonorientable surfaces
Paolo Bellingeri, Sylvain Gervais
We prove that the n th pure braid group of a nonorientable surface (closed or with boundary, but different from RP2) is residually 2-finite. Consequently, this group is residually…
Surface framed braids
Paolo Bellingeri, Sylvain Gervais
In this paper we introduce the framed pure braid group on strands of an oriented surface, a topological generalisation of the pure braid group . We give different equivale…
Lower central series for surface braid groups
Paolo Bellingeri, Sylvain Gervais, John Guaschi
We determine the lower central series and corresponding residual properties for braid groups and pure braid groups of orientable surfaces.
A finite presentation of the mapping class group of an oriented surface
Sylvain Gervais
We give a finite presentation of the mapping class group of an oriented (possibly bounded) surface of genus greater or equal than 1, considering Dehn twists on a very simple set of…
