Abstract

Analytic quasi-periodic skew-systems with close to constant coefficients and with Diophantine frequencies seem to be, in a measure theoretical sense, ‘generically’ reducible. In this paper we show that such systems are, in a topological sense, generically uniquely ergodic and, in particular, non-reducible.
