Profinite isomorphisms and fixed-point properties
We describe a flexible construction that produces triples of finitely generated, residually finite groups M ãÑ P ãÑ Γ, where the maps induce isomorphisms of profinite completions Mx – Pp – Γ, but p M and Γ have Serre’s property FA while P does not. In this construction, P is finitely presented and Γ...
