Add to ORKGAbstract. Certain classes of automorphisms of reduced amalgamated free products of C algebras are shown to have Voiculescu{Brown topological entropy zero. Also, for automorphisms of exact C {algebras, the Connes{Narnhofer{Thirring entropy is shown to be bounded above by the Voiculescu{Brown entropy. These facts are applied to generalize Strmer's result about the entropy of automorphisms of the II 1 {factor of a free group. x1. Introduction. Kolmogorov's entropy invariant was extended by Connes and Srmer [5] to an invariant h () for an automorphism of a von Neumann algebra with a given normal faithful tracia
