Dynamics and eigenvalues in dimension zero

Abstract

Let XX be a compact, metric and totally disconnected space and let f:XXf:X\to X be a continuos map. We relate the eigenvalues of f:Hˇ0(X;C)Hˇ0(X;C)f_{*}:\check{H}_{0}(X;\mathbb{C})\to\check{H}_{0}(X;\mathbb{C}) to dynamical properties of ff, roughly showing that if the dynamics is complicated then every complex number of modulus different from 0,1 is an eigenvalue. This stands in contrast with the classical Manning's inequality.
