The Birman exact sequence for 3-manifolds

Jessica Banks (University of Hull)

Monday 9th February, 2015 16:00-17:00 Maths 204


This talk will consider the Birman exact sequence for a 3-manifold M. In particular, we will show there is an exact sequence 1π1(M,p)Mod(M,p)Mod(M)1 unless M is foliated by circles. We will also discuss what can be said when M is of this form.
