Composition operators between Nevanlinna classes and Bergman spaces with weights

Abstract

We investigate composition operators between spaces of analytic functions on the unit disk $\De$ in the complex plane. The spaces we consider are the weighted Nevanlinna class $\cN_\al$, which consists of all analytic functions $f$ on $\De$ such that $\int\limits_\De\log^+ |f(z)|(1-|z|^2)^\al {\, {\rm d}x \, {\rm d}y}<\iy$, and the corresponding weighted Bergman spaces $\cA^p_\al$, $-1<\al<\iy$, $0-1$, $0<q<\iy$. We characterize, in function theoretic terms, when the composition operator $\Cf:f\mt f\ci\vf$ induced by an analytic function $\vf:\De\to\De$ defines an operator $X\to Y$ which is continuous, respectively compact, respectively order bounded.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
