Explicit presentations for exceptional braid groups

David Bessis, Jean Michel

We give presentations for the braid groups associated with the complex reflection groups $G_{24}$ and $G_{27}$ . For the cases of $G_{29}$ , $G_{31}$ , $G_{33}$ and $G_{34}$ , we give…

Garside structure for the braid group of G(e,e,r)

David Bessis, Ruth Corran

We give a new presentation of the braid group $B$ of the complex reflection group $G (e, e, r)$ which is positive and homogeneous, and for which the generators map to reflections in t…
