On the self-similarity index of $p$ -adic analytic pro- $p$ groups

Francesco Noseda, Ilir Snopce

Let $p$ be a prime. We say that a pro- $p$ group is self-similar of index $p^{k}$ if it admits a faithful self-similar action on a $p^{k}$ -ary regular rooted tree such that the action i…

Index-stable compact $p$ -adic analytic groups

Francesco Noseda, Ilir Snopce, Jean-Pierre Serre

A profinite group is index-stable if any two isomorphic open subgroups have the same index. Let $p$ be a prime, and let $G$ be a compact $p$ -adic analytic group with associated $\m…

On hereditarily self-similar $p$ -adic analytic pro- $p$ groups

Francesco Noseda, Ilir Snopce

A non-trivial finitely generated pro- $p$ group $G$ is said to be strongly hereditarily self-similar of index $p$ if every non-trivial finitely generated closed subgroup of $G$ admi…
