Composition followed by differentiation between weighted Bergman spaces and weighted Banach spaces of holomorphic functions

Authors: Elke Wolf

Abstract

Let $\phi$ be an analytic self-map of the open unit disk $\mathbb{D}$ in the complex plane. Such a map induces through composition a linear composition operator $C_{\phi}: f \mapsto f \circ \phi$. We are interested in the combination of $C_{\phi}$ weith the differentiation operator $D$, that is in the operator $D C_{\phi}: f \mapsto \phi' \cdot (f \circ \phi)$ acting between weighted Bergman spaces and weighted Banach spaces of holomorphic functions.
