Bloch-Sobolev Spaces and Analytic Composition Operators

Bloch-Sobolev Spaces and Analytic Composition Operators We introduce the so-called Bloch-Sobolev function spaces and show that these spaces have nice closure properties. We also characterize the boundedness and compactness of a composition operator Cø (with analytic symbol ø between two subdomains Ω, Ω′ ⊊ ℝ2) acting between two Bloch-Sobolev spaces. As a by-product we obtain a characterization of those analytic mappings ø: Ω→ Ω′, which are uniformly continuous with respect to the quasihyperbolic metrics in Ω and Ω′. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Computational Methods and Function Theory Springer Journals

Abstract

We introduce the so-called Bloch-Sobolev function spaces and show that these spaces have nice closure properties. We also characterize the boundedness and compactness of a composition operator Cø (with analytic symbol ø between two subdomains Ω, Ω′ ⊊ ℝ2) acting between two Bloch-Sobolev spaces. As a by-product we obtain a characterization of those analytic mappings ø: Ω→ Ω′, which are uniformly continuous with respect to the quasihyperbolic metrics in Ω and Ω′.
