Sadek AL Harbat

We define a tower of injections of $B ~$ -type (resp. $D ~$ -type) Coxeter groups $W (B ~_{n})$ (resp. $W (D ~_{n})$ ) for $n \geq 3$ . Let $W^{c} (B ~_{n})$ (resp…

Sadek Al Harbat

We view the $A ~$ -type affine braid group as a subgroup of the $B$ -type braid group. We show that the $A ~$ -type affine braid group surjects onto the $A$ -type braid gro…
