Topological Wiener-Wintner ergodic theorem with polynomial weights
speaker: Ai-Hua Fan (Univ. Picardie, France/CCNU, China)abstract: For a totally uniquely ergodic dynamical system, we prove a topological Wiener-Wintner ergodic theorem with polynomial weights under the coincidence of the quasi-discrete spectrums of the system in both senses of Abramov and of Hahn-Parry. The result applies to ergodic nilsystems. Fully oscillating sequences can then be constructed on nilmanifolds.
