Spectral characterization of weak topological transitivity

Original Paper


Given a bounded linear operator S on a real Banach space X, we characterize weak topological transitivity of the operator families \({\lbrace S^t \mid t \in {\mathbb N}\rbrace}\), \({\lbrace \kappa S^t\mid\, t \in {\mathbb N},\, \kappa >0 \rbrace}\), and \({\lbrace \kappa S^t\mid\, t \in {\mathbb N},\, \kappa \in {\mathbb R}\rbrace}\) in terms of the point spectrum of the dual operator S*.
