The finitely generated intersection property in fundamental groups of graphs of groups

Jordi Delgado, Marco Linton, Jone Lopez de Gamiz Zearra +2

A group $G$ is said to satisfy the finitely generated intersection property (f.g.i.p.) if the intersection of any two finitely generated subgroups of $G$ is again finitely generate…

Pullbacks and intersections in categories of graphs of groups

Jordi Delgado, Marco Linton, Jone Lopez de Gamiz Zearra +2

We develop a categorical framework for studying graphs of groups and their morphisms, with emphasis on pullbacks. More precisely, building on classical work by Serre and Bass, we g…

On the Bieri-Neumann-Strebel-Renz invariants and limit groups over Droms RAAGs

Dessislava H. Kochloukova, Jone Lopez de Gamiz Zearra

For a group $G$ that is a limit group over Droms RAAGs such that $G$ has trivial center, we show that $Σ^{1} (G) = \emptyset = Σ^{1} (G, Q)$ . For a group $H$ that is a finitely…
