Wreath-like products of groups and their von Neumann algebras II: Outer automorphisms

I. Chifan, A. Ioana, D. Osin +1

Given a countable group $G$, let $\mathrm{L}(G)$ denote its von Neumann algebra. For a wide class of ICC groups with Kazhdan's property (T), we confirm a conjecture of V.F.R. Jones as…
