Torsion conjecture for virtual Artin groups
Torsion conjecture for virtual Artin groups
Let be a Coxeter graph, let be the associated virtual Artin group, and let denote its embedded copy of the associated Coxeter group. Torsion conjecture for virtual Artin groups. Every finite subgroup of is conjugated into a subgroup of . This is unknown even for virtual braid groups, but is proved in the paper for locally reducible Coxeter graphs.
