Relative profinite rigidity of Baumslag-Solitar groups
Daxun Wang
We prove that each residually finite Baumslag-Solitar group can be distinguished by its finite quotients from all other residually finite Baumslag-Solitar groups.

The isomorphism problem for small-rose generalized Baumslag-Solitar groups
Daxun Wang
A generalized Baumslag-Solitar group is a finitely generated group that acts on a tree with infinite-cyclic vertex and edge stabilizers. In this paper, we show that the isomorphism…
