Representations of Coxeter groups over fusion rings and hyperplane complements

Edmund Heng, Luis Paris

We study faithful realisations of Coxeter groups over fusion rings and study Vinberg systems associated to them. We show that they induce embeddings of hyperplane complements, whic…

Normalisers of parabolic subgroups of Artin--Tits groups and Tits cone intersections

Owen Garnier, Edmund Heng, Anthony Licata +1

Let be a Coxeter diagram and let . Motivated by 3-fold flops, Iyama and Wemyss study the hyperplane arrangement in the Tits cone intersection of , which is a…

Introduction to stability conditions and its relation to the conjecture for Artin groups

Edmund Heng

We give a brief introduction to the relationship between Bridgeland stability conditions and the conjecture for Artin groups. These notes have been written as pre-reading…

Coxeter embeddings are injective

Ben Elias, Edmund Heng

We show that certain embeddings of Coxeter groups within other Coxeter groups are injective using the notion of Coxeter partitions. Moreover, we study Lusztig's partitions, which a…
