Dynamical entropy of quasifree automorphisms. (English) Zbl 0628.46065

The dynamical entropy, as defined in: A. Connes, H. Narnhofer and W. Thirring, Commun. Math. Phys. 112, 691-719 (1987) is calculated for quasi free automorphisms and quasi free states and shown to be the entropy of the shift created by the group velocity.
