Profinite genus of HNN-extensions with finite associated subgroups
V. R. de Bessa, A. L. P. Porto, P. A. Zalesskii
We study the profinite genus of HNN-extensions whose associated subgroups are finite. We give precise formulas for the number of isomorphism classes of HNN(G,H,K,t,f) and of its pr…
Profinite genus of free products with finite amalgamation
Vagner R. de Bessa, Anderson L. P. Porto, Pavel A. Zalesskii
A finitely generated residually finite group is an -group if any action of its profinite completion on a profinite tree with finite edge stabilizers…
The profinite completion of accessible groups
Vagner R. de Bessa, Anderson L. P. Porto, Pavel A. Zalesskii
We introduce a class $\A$ of finitely generated residually finite accessible groups with some natural restriction on one-ended vertex groups in their JSJ-decompositions. We prove t…
