RAAG subgroups of RAAGs

Presented by: 
Karen Vogtmann
Thursday 13th April 2017 - 11:00 to 12:00
INI Seminar Room 2
Motivated by work of Grunewald and Lubotzky on virtual representations of Aut(F_n), we address the question of when a finite index normal subgroup of a RAAG is itself a RAAG.   Joint work with Beatrice Pozzetti.
