Braid groups and the group of homeomorphisms of a surface

TLDR
In this article, the authors give finite presentations for the braid groups on all closed 2-manifolds except S2 and P2, and show that they can be found on R2, S2, P2 and S2.
Abstract
Braid groups on the plane were denned by Artin(1) in 1925. More recently Fox(8) defined braid groups on arbitrary topological spaces, the situation being particularly interesting if the space is a 2-manifold. Presentations of the braid groups on R2, S2 and P2 can be found in (2), (6) and (13) respectively, and some general results on braid groups of compact 2-manifolds can be found in (7). In section 1 of this paper, we give finite presentations for the braid groups on all closed 2-manifolds except S2 and P2.

The theory of braids.

TL;DR: The theory of braids as discussed by the authors shows the interplay of two disciplines of pure mathematics? topology, used in the definition of Braids, and the theory of groups used in their treatment.
