Stability of amalgamated free products and HNN extensions
Maria Gerasimova, Konstantin Shchepin
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…

Virtually free groups are -Schatten stable
Maria Gerasimova, Konstantin Shchepin
In this note we prove that finitely generated virtually free groups are stable with respect to a normalized -Schatten norm for . In particular, this implies th…
