On suspensions, and conjugacy of a few more automorphisms of free groups

François Dahmani

Résumé

In a previous work, we remarked that the conjugacy problem for pairs of atoroidal automorphisms of a free group was solvable by mean of the isomorphism problem for hyperbolic groups and an orbit problem for the automorphism group of their suspensions (i.e. their semidirect product with ℤ for the relevant structural automorphism). We consider the same problem a few more automorphisms of free groups, those that produce relatively hyperbolic suspensions that do not split over a parabolic subgroup.
