Outer Automorphisms of the Generic Dynamics Factor

Let A be the generic dynamics factor. Since A is a quotient of the Borel*- envelope of the Fermion algebra it is hyperfinite. Let Out AsAut ArInn A be the outer automorphism group of A. Among other more general results it is shown that every countable group can be isomorphically embedded in Out A; there exist continuum many elements of Out A corresponding to aperiodic outer automorphisms; for each natural number pG2 there exist continuum many elements of Out A corresponding to periodic automorphisms of order p
