Residual finiteness of graphs of free groups with cyclic edge groups
Apparaît dans la collection : Geometric Group Theory around Cube Complexes / La Théorie Geometrique des Groupes autour des Complexes Cubiques
We will prove a finite graph of free groups with cyclic edge groups is residually finite if and only if its Baumslag-Solitar subgroups are all residually finite. Moreover, we will show that this property can be easily detected from the defining graph of groups structure. Joint with Adrien Abgrall.
