A pro-$p$ version of Sela's accessibility and Poincar\'e duality pro-$p$ groups

Group Theory 2023-02-14 v1

Abstract

We prove a pro-pp version of Sela's theorem stating that a finitely generated group is kk-acylindrically accessible. This result is then used to prove that PDn\mathrm{PD}^n pro-pp groups admit a unique kk-acylindrical JSJ-decomposition.
