Abstract
We consider aperiodic shifts of finite type sigma with an equilibrium state m and associated skew-products sigma(f) where f:X --> G is Holder and G is a compact Lie group. We show that generically sigma(f) is weak-mixing and give constructive methods for achieving weak-mixing by perturbing an arbitrary f at a finite number of small neighbourhoods. When sigma(f) is not ergodic we describe the (closed) ergodic decomposition precisely. The key result shows that certain measurable eigenfunctions are essentially Holder continuous. This leads to conditions for weak-mixing or ergodicity in terms of a functional equation which involves Holder rather than measurable functions.
