Strongly contracting axes for fully irreducible automorphisms of Generalized Baumslag-Solitar groups
Chloé Papin
Similarly to the action of on Outer Space, the outer automorphism group of a Generalized Baumslag Solitar group acts on a deformation space endowed with the Lipschitz me…

Detection of fully irreducible automorphisms in generalized Baumslag-Solitar groups
Chloé Papin
We define fully irreducible automorphisms of generalized Baumslag-Solitar groups in analogy with fully irreducible automorphisms of free groups. We first obtain a characterization…

Whitehead algorithm for automorphisms of generalized Baumslag-Solitar groups
Chloé Papin
In analogy with the free factors of a free group we define special factors of Generalized Baumslag-Solitar (GBS) groups as non-cyclic subgroups which appear in splittings over infi…
