Composition operators from Nevanlinna type spaces to Bloch type spaces

Abstract

Let $X$ and $Y$ be complete metric spaces of analytic functions over the unit disk in the complex plane. A linear operator $T: X \to Y$ is a bounded operator with respect to metric balls if $T$ takes every metric ball in $X$ into a metric ball in $Y$. We also say that $T$ is metrically compact if it takes every metric ball in $X$ into a relatively compact subset in $Y$. In this paper we will consider these properties for composition operators from Nevanlinna type spaces to Bloch type spaces.
