Title: Solidity results in von Neumann algebras
Abstract:
We show that the von Neumann algebra L(G) of a hyperbolic group G is solid, meaning: for any diffuse subalgebra A of L(G), the relative commutant of A inside L(G) is amenable (theorem due to N. Ozawa, 2003). The proof is based on a different and recent approach following the work of Boutonnet and Carderi, 2014.
