We exhibit some automorphism bases for the enumeration degrees, and we derive some consequences relative to the automorphisms of the enumeration degrees.

We modify slightly Voiculescu's definition of approximation entropy of automorphisms of finite von Neumann algebras and compare it with the entropy of Connes and Sto% rmer. For this the notion of a generator is relevant, as its existence implies that the entropies coincide. Special emphasis is put o

✍ H. Narnhofer; W. Thirring πŸ“‚ Article πŸ“… 1987 πŸ› Springer 🌐 English βš– 330 KB

The dynamical entropy of quasifree automorphisms and quasifree states is calculated and shown to be the entropy of the shift created by the group velocity. Some continuity properties are proved.
