Title: Hilbert-Schmidt stability of some non-amenable groups

Abstract: We will discuss the notion of Hilbert-Schmidt stability of groups, its connection to C*-algebras, and various examples of stable and non-stable groups. After this we will discuss Hilbert-Schmidt stability of virtually free groups and some results about stability of more general amalgamated products and HNN extensions.
