Topological Wiener–Wintner theorems for amenable operator semigroups
Published online by Cambridge University Press: 04 April 2013
Abstract
Inspired by topological Wiener–Wintner theorems we study the mean ergodicity of amenable semigroups of Markov operators on $C(K)$ and show the connection to the convergence of strong and weak ergodic nets. The results are then used to characterize mean ergodicity of Koopman semigroups corresponding to skew product actions on compact group extensions.
