A new Garside structure for the braid groups of type (<i>e, e, r</i> )
A new Garside structure for the braid groups of type (<i>e, e, r</i> )
We describe a new presentation for the complex reflection groups of type (e, e, r) and their braid groups. A diagram for this presentation is proposed. The presentation is a monoid presentation that is shown to give rise to a Garside structure. This structure has since been used in understanding …
