Asymptotic Behavior of Individual Orbits of Discrete Systems

3:30 PM, KED B005, University of Ottawa, Ottawa

Abstract: In this talk I will speak about individual versions of the Katznelson- Tzafriri Theorem on the asymptotic behavior of orbits of power- bounded operators and related stability results. The obtained results based on elementary proofs extend previous results on the subject. We will further the techniques of spectral theory of sequences to study the stability of discrete systems.
