Linear representations, crystallographic quotients, and twisted conjugacy of virtual Artin groups
Neeraj Kumar Dhanwani, Pravin Kumar, Tushar Kanta Naik +1
Virtual Artin groups were recently introduced by Bellingeri, Paris, and Thiel as broad generalizations of the well-known virtual braid groups. For each Coxeter graph , they def…
