Finite Coxeter Groups and Generalized Elnitsky Tilings (2111.10669v4)
Published 20 Nov 2021 in math.GR and math.CO
Abstract: In [5], Elnitsky constructed three elegant bijections between classes of reduced words for Type $\mathrm{A}$, $\mathrm{B}$ and $\mathrm{D}$ families of Coxeter groups and certain tilings of polygons. This paper offers a particular generalization of this concept to all finite Coxeter Groups in terms of embeddings into the Symmetric Group. [5] Elnitsky, Serge.
