The braid group Bn is not a quotient of a quasi-Coxeter interval group of type Dn

Barbara Baumeister, Luis Paris, Sarah Rees

We prove that, for $n \geq 5$ , an interval group associated with a proper quasi-Coxeter element of the Coxeter group of type $D_{n}$ admits no surjective homomorphism onto the braid g…

Interval groups related to finite Coxeter groups I

Barbara Baumeister, Georges Neaime, Sarah Rees

We derive presentations of the interval groups related to all quasi-Coxeter elements in the Coxeter group of type $D_{n}$ . Type $D_{n}$ is the only infinite family of finite Coxeter gr…
