Bloch-to-Hardy composition operators

Evgueni Doubtsov, Andrei Petrov (2013)

Open Mathematics

Similarity:

Let φ be a holomorphic mapping between complex unit balls. We characterize those regular φ for which the composition operators C φ: f ↦ f ○ φ map the Bloch space into the Hardy space.

Holomorphic Bloch spaces on the unit ball in C n

A. V. Harutyunyan, Wolfgang Lusky (2009)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

This work is an introduction to anisotropic spaces of holomorphic functions, which have ω -weight and are generalizations of Bloch spaces on a unit ball. We describe the holomorphic Bloch space in terms of the corresponding L ω ∞ space. We establish a description of ( A p ( ω ) ) * via the Bloch classes for all 0 < p ≤ 1 .

Bernstein-type operators on the half line

Antonio Attalienti, Michele Campiti (2002)

Czechoslovak Mathematical Journal

Similarity:

We define Bernstein-type operators on the half line [ 0 , + ∞ [ by means of two sequences of strictly positive real numbers. After studying their approximation properties, we also establish a Voronovskaja-type result with respect to a suitable weighted norm.
