Generalized Stallings' decomposition theorem for pro- $p$ groups

Mattheus Aguiar, Pavel Zalesski

The celebrated Stallings' decomposition theorem states that the splitting of a finite index subgroup $H$ of a finitely generated group $G$ as an amalgamated free product or an HNN-…

The profinite completion of the fundamental group of infinite graphs of groups

Mattheus Aguiar, Pavel Zalesski

Let $(G, Γ)$ be an abstract graph of finite groups. If $Γ$ is finite, we can construct a profinite graph of groups in a natural way $(G^, Γ)$ , where $\hat{\m…
