Let $W$ be a finite reflection group containing $-1$, let $G$ be its Dynkin diagram, and let $\bar G$ be an orientation. Form the Coxeter element $c$ from the oriented diagram, ord…

Let $W$ be a well-generated reflection group acting on a complex vector space $V$. A frame $\Lambda$ is the auxiliary structure used to define the properties strongly stratified an…

Let $W$ be a well-generated reflection group acting on a complex vector space $V$. A generating set $R$ is well-generating when it generates $W$ and has cardinality $\dim V$. The s…
