Stability of amalgamated free products and HNN extensions

Group Theory 2023-07-14 v2 Operator Algebras

Abstract

We study stability of amalgamated free products and HNN extensions of stable groups over finite groups. We focus on operator norm stability, Hilbert-Schmidt stability and stability in permutations. We provide many new examples of stable (or flexibly stable) non-amenable groups.
