Dyer groups are a class that generalizes well-known families of groups such as Coxeter groups and RAAGs. There are some properties of these groups that extend naturally to the wider class, and one can use similar techniques to study them. In this talk, we will first introduce all these families of groups. Then, following previous work by Krammer in Coxeter groups and by Paris in Artin groups, we will construct a graph that gives an algorithm which decides whether two parabolic subgroups of a Dyer group are conjugated. This is a joint work with María Cumplido and Mireille Soergel.
