Group automorphisms with few and with many periodic points

Abstract

For any C[0,]C\in[0,\infty] a compact group automorphism T:XXT:X\to X is constructed with the property that 1nlog{xXTn(x)=x}C. \frac{1}{n}\log|\{x\in X\mid T^n(x)=x\}|\longrightarrow C. This may be interpreted as a combinatorial analogue of the (still open) problem of whether compact group automorphisms exist with any given topological entropy.
