Conjugacy stability of parabolic subgroups of Artin-Tits groups of spherical type
arXiv:1807.07198
Abstract
We give a complete classification of conjugacy stable parabolic subgroups of Artin-Tits groups of spherical type. This answers a question posed by Ivan Marin and generalizes a theorem obtained by Juan González-Meneses in the specific case of Artin braid groups.
Preliminary version; any comment welcome
