A famous problem going back to their work is whether the von Neumann algebras L( F n ), associated with the free groups on n generators, are non-isomorphic for different n’s.

In [7], Fidaleo and Mukhamedov showed that the von Neumann algebras generated by faithful translation-invariant quantum Markov states are factors of type
