One-relator quotients of partially commutative groups
Vendredi, 23 Mars, 2018 - 10:30
Résumé : 

I will describe how methods of small cancellation theory for HNN-extensions can be applied in the case of partially commutative groups  (RAAGs). The result is a Freiheitssatz, for one-relator quotients, where the relator is a proper power, and satisfies some additional conditions.
