Braid group of Z^n
If you have a question about this talk, please contact David Craven.
I will talk on my 2007 paper ‘The braid group of Zn’. The motivation for defining this group is that it is a missing link between the usual braid group and mapping class groups of higher genus surfaces. Braid groups were shown to be Garside in 1969. I shall show that the braid group of Zn is Garside. Work in progress, that I will not discuss in detail, is a Garside structure on the mapping class groups.
