Characterization of weighted Hardy spaces on which all composition operators are bounded

Pascal Lefèvre, Daniel Li, Hervé Queffélec +1

We give a complete characterization of the sequences $β = (β_{n})$ of positive numbers for which all composition operators on $H^{2} (β)$ are bounded, where $H^{2} (β)$ is the space of an…

On some questions about composition operators on weighted Hardy spaces

Pascal Lefèvre, Daniel Li, Hervé Queffélec +1

We first consider some questions raised by N. Zorboska in her thesis. In particular she asked for which sequences $β$ every symbol $φ : D \to D$ with $φ\in H^…
