Positive entropy,We begin this section with a brief discussion of entropy for a single automorphism . of a compact group ., in which we prove that every ergodic automorphism of an infinite, compact group has positive entropy, and that automorphisms with zero entropy have a very degenerate structure.

Just as compact, abelian groups like . = ?./?. have automorphisms with very intricate dynamical properties, there is an abundance of examples of interesting ?.-actions by automorphisms of compact abelian groups. In this section we introduce

,So klingt unsere Stimme für andere,(Definition 5.5), and Example 5.6 (1) shows that the d.c.c. cannot be dropped in general. In this section we investigate the density of the set of periodic points for a ?.-action . by automorphisms of compact group . satisfying the d.c.c. We begin with two examples which show that—if . is non-abelia
